Full Text Bug Listing

Emerged kpdf with -Os and every time I opened a pdf got "Program recieved 
segfault" I couldn't backtrace. So i searched aroung and saw a post on Gentoo 
forums pointing out that it may be due to -Os CFLAGS so I compiled with -O2 and 
works prefectly.

Reproducible: Always
Steps to Reproduce:
1.Change CFLAGS to -Os
2.emerge -av =kde-base/kpdf-3.5.0-r1
3.Open pdf document

Actual Results:  
segfault cannot backtrace

Expected Results:  
Opened and viewed pdf document.

My CFLAGS are -Os (normally) -fomit-frame-pointer -pipe nothing in my system is 
riced out ;) running gcc 3.4.4 with x86 stable TK.

heres emerge --info

Works fine here with -Os... 
 

maybe its gcc 3.4.4? 

must be local

I have also experienced crashes in KPDF when compiled with -Os. Not all my 
pdfs caused it to crash, and those that did were not especially large. An 
example pdf file causing crashes is the "GNU Privacy Handbook" (the version 
created in 08/08/2000 and produced by pdfTex 13.c, but probably other versions 
as well). 
This kind of behavior is also reported in bugs 112854 and 115048 in KDE's  
bugzilla. 
IMHO, I think you should play it safe and filter out the "-Os" optimization  
for KPDF.  

glad to hear it wasnt local =) for me -O2 fixed everything maybe the ebuild
should force -O2?

im reopening this bug

i can confirm this, everything works fine except pdf, kpdf/xpdf both crash on
almost any pdf file

Hi,

while I do experience crahses with several pdfs on my desktop
CFLAGS="-march=athlon-xp -Os -pipe -fomit-frame-pointer"
the same files open fine on my laptop
CFLAGS="-march=pentium-m -Os -pipe -fomit-frame-pointer"

recompiling kpdf with '-O2 ' on the desktop does solves the problem.

It seems to me that only certain combinations with '-Os' do crash kpdf.

--> this is the same for both machines.

Enough evidence, thanks for your reports. :)
