Bugzilla Bug 122681

Emerging sci-libs/cln-1.1.10 yields :
[...]
>>> Source unpacked.
/usr/portage/sci-libs/cln/cln-1.1.10.ebuild: line 25: repace-flags: command not
found
checking whether make sets $(MAKE)... yes
[...]

Emerge then goes on without any further error, but if you are in the situation
where replacing the -Os CFLAG by -O2 is needed, then applications needing cln
segfault. All that is needed is to change 'repace-flags' with 'replace-flags'
(fourth line in the src_compile() function).

Plus, since the situation regarding -Os and -ffast-math is identical in the
stable version of cln (I've just verified this), wouldn't be nice (necessary?)
if cln-1.1.6 had the same replace-flags statement as cln-1.1.10 ?

Fixed in portage CVS. Thanks for reporting!

Sorry, I missed that bit and I'll have a look at it.

Could you please post your emerge info and the exact CFLAGS that
produce this problem. I cannot reproduce it with -Os -ffast-math
on my box. 

Thanks,
Markus

I'm sorry about the mistakes. First the multiple postings, and then I tell you
about -ffast-math when I meant -fomit-frame-pointer. Now I'll know I shouldn't
report bugs on monday mornings.

I'm the one who reported bug #112741. I found out that cln was sensitive to a
combination of -Os and -fomit-frame-pointer. One alone is OK, both at the same
time isn't. At that time I wrote :

> -Os -fomit-frame-pointer -> segfault
> -0s -> OK
> -O2 -fomit-frame-pointer -> OK

This was about cln-1.1.10. So, to rephrase my question of yesterday, since the
problem is identical with cln-1.1.6, shouldn't we replace -Os with -O2 in
cln-1.1.6 too ?

Here is my emerge info. It is a recent and fully stable installation.

I have just checked that if I change -Os in -O2 then cln works. On another
system I have the more exotic flags below, and just changing -Os into -O2 also
fixes the issue:

CFLAGS="-march=athlon-xp -pipe -Os -fomit-frame-pointer -fno-ident -fforce-addr
-ftracer -fweb -falign-functions=64 -ffast-math"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS} -fvisibility-inlines-hidden -D_FILE_OFFSET_BITS=64"
LDFLAGS="-Wl,-O1 -Wl,--sort-common"

Best regards,
Denis.
