Bugzilla Bug 99998

The write command seems not to work in cdrdao-1.2.0 anymore. When trying to
write anything, cdrdao just exits without any message, like this:

root@pippo ~ # cdrdao write --device ATA:1,0,0 --driver generic-mmc-raw hein.toc
Cdrdao version 1.2.0 - (C) Andreas Mueller <andreas@daneb.de>
  SCSI interface library - (C) Joerg Schilling
  Paranoia DAE library - (C) Monty

Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables.

Reproducible: Always
Steps to Reproduce:
1. cdrdao write ...
Actual Results:  
cdrdao exits without writing.

Expected Results:  
cdrdao should have written the cd or given an error message.

Using gcc-3.3.5.20050130-r1 (x86) it is only broken with CFLAGS="-O2". Without
it works fine again.

I have now tried using gcc-3.4.4 (~x86) to compile cdrdao-1.2.0 with -O2 and
even -O3 and it works.

This occurs for me too.

Using gcc-3.3.5.20050130-r1 and CFLAGS="-march=pentium4 -Os" - cdrdao 1.2.0 just
exits on the write command. (This never occurred with 1.1.9)

Setting my CFLAGS to simply "" got it working.

My mustard to this issue, because I temporary installed cdrdao 1.1.9-r2 back to
burn a cd with cdrdao.

# --- code snipped (may not work, but shows how it is fixable(hopefully) ) ---
gccver=`gcc -v 2>&1 | grep gcc-3.3.5-20050130`
if [ -n ${gccver} ]; then
    filter-flags '-O2'
    einfo "U are using gcc-3.3.5 in this version -O2 has a problem, so removed
from CFLAGS"
fi

I have this on a amd64 and no playing with CFLAGS made any difference still not
working

Same problem here, with version 1.2.0, -O2 and gcc-3.3.5-20050130 on x86. I've
had no issues with previous versions. I'll try re-emerging it with different
CFLAGS and see if it works. 

So I tested with -O3, -O2 and -Os without success. But removing any
optimization
switches - which makes GCC fallback to O0 - does the trick and cdrdao now
works.
Looks like a cdrdao-specific problem, non-ebuild/gentoo related.

cdrdao-1.1.9 works fine for me. suggest mask / stripping of O2 (untested by me)
until issue is resolved.

You can use -O2 if you also use -fno-inline.  The problem code appears to be in
util.cc where stat has been inlined.  If anybody know x86 assembly, the could
perhaps figure out if the problem is in gcc or in glib.

is it possible to modify the 1.2.0 ebuild so that -fno-inline is used ?

Just adding -fno-inline to my CFLAGS didn't seem to fix the problem for me.   
(CFLAGS="-O2 -march=i686 -fno-inline -ftracer -fomit-frame-pointer -pipe") 
 
Getting rid of -ftracer and -fomit-frame-pointer didn't work.  Getting rid of 
everything (except -pipe) did. 
 

-fno-inline fixed it for me. I tried it with no use flags but -pipe and it
actually caused this error.

Updated ebuild

Same problem with default ebuild (emerge --info below).
This is a mostly C++ app, so need to set CXXFLAGS as well as CFLAGS - just
messing with CFLAGS won't help (I tried!)
CFLAGS and CXXFLAGS I tried:
"": Works
"-fno-inline": Works
"-march=athlon-xp -pipe -msse -mmmx -m3dnow -fomit-frame-pointer -fno-inline":
Works
"-march=athlon-xp -pipe -msse -mmmx -m3dnow -fomit-frame-pointer": Broken
"-O3 -march=athlon-xp -pipe -msse -mmmx -m3dnow -fomit-frame-pointer
-fno-inline":
Broken

So it seems -O is a breaker, and -fno-inline is required, unless all other
flags are off.
Ebuild removing all -O flags and addeing -fno-inline attached.

FYI, I also have the problem of cdrdao 1.2.0 exiting without doing anything and
with no error messages.  Downgrading to cdrdao-1.1.7-r3 solved the problem.
1.2.0 is now in my package.mask...

adding the -fno-inline flag to CFLAGS/CXXFLAGS and removing -O from 
CFLAGS/CXXFLAGS and recompiling cdrdao-1.2.0 fixed the problem for me as well. 

Hopefully fixed on cdrdao-1.2.0-r1 version in cvs.
Reopen if you still have the same problems.

reopen per Heiko's bug

*** Bug 111695 has been marked as a duplicate of this bug. ***

On my machine, AMD64 (see emerge info below), cdrdao-1.2.0-r1 still refuses   
to burn any CDs. I've tried with my normal CFLAGS, and also with:   
   
CFLAGS="-pipe" emerge --oneshot -v cdrdao   
   
reduced CFLAGS, but to no avail.   
   
Reproducible: Always   
Steps to Reproduce:   
1. get a cue image   
2. burn with cdrdao write ...   
   
Actual Results:

This was previously posted as bug #111695. 

cdrdao-1.2.1 will be out soon i hope they fix this issue. I will investigate
this further again and looks like the problems aren't just on CFLAGS. Anyone
with the this problem can check if it still exists on -r1 version running on x86 ?

Path to add a missing return statement

This patch adds a missing return statement to a function returning a bool. 
Without this the return value is essentially random, and the write command tend
to return immediately.	This should be the _real_ fix for this bug, rather than
the CFLAGS/CXXFLAGS tweaks which seem to be hit and miss with many users.

Verified working on my AMD64 Gentoo system.

because i couldn't reproduce this bug i had to analyze all replys here and do
the proper changes but looks like that a few users complain about different
things than the last replys. I'm checking your patch but i maybe will apply the
upstream patch to hopefully fix this bug. Can everybody involved in this bug
test the previous patch to make sure we don't have this bug open again ?

http://dev.gentoo.org/~metalgod/ebuilds/cdrdao-1.2.0-trackfix.patch here is the
patch everyone with this bug can apply this patch and see if its fixed ?

This patch is on the latest version 1.2.1 that is in CVS. Please test and
reopen
if you guys have the same issue.

Thanks all
