Backtrace posted
Which test image did you use, so I can try to reproduce it?
(In reply to comment #5) > Which test image did you use, so I can try to reproduce it? It didn't seem to matter, I just chose a few at random from locate .jpg. As you can see in the backtrace I used /usr/kde/3.5/share/wallpapers/blue-bend.jpg for one of them. I was able to reproduce this on 3 different Gentoo installs.
I haven't been able to reproduce it with the same image file. netpbm: 10.36.0[14:08:12 10/08/06][-svga jpeg tiff png xml zlib] gocr: 0.41[20:01:43 09/07/06][gtk -doc] In your first comment, the emerge command says 'U', which means that you do not have netpbm-10.36.0 yet, are you sure that it is this version that you are having problems with?

Yes, definitely. The following is all I did on a system without it installed to reproduce the error: ~ # echo "media-libs/netpbm ~x86" >> /etc/portage/package.keywords ~ # emerge -pv netpbm gocr [ebuild N ] media-libs/urt-3.1b-r1 USE="gif -X -gs -tiff" 0 kB [ebuild N ] media-libs/jbigkit-1.6-r1 0 kB [ebuild N ] media-libs/jasper-1.701.0 USE="jpeg -opengl" 0 kB [ebuild N ] media-libs/netpbm-10.36.0 USE="jpeg png xml zlib -svga -tiff" 0 kB [ebuild N ] app-text/gocr-0.40-r2 USE="-doc -gtk" 0 kB ~ # emerge netpbm gocr ~ # gocr -i /var/www/mail/themes/horde/graphics/mobile/display.jpg Segmentation fault
Then I can definitely not reproduce it, I'm afraid. I'll ask someone to try on an amd64 system. Can you provide a full log of emerging both netpbm and gocr and a fresh system, please?

One is running stable with CFLAGS="-mtune=athlon-xp -O3 -pipe -fomit-frame-pointer".

Created attachment 100766 [details] full log of netpbm and gocr emerge
Created attachment 100767 [details] full log of netpbm-10.36.0 and gocr emerge I just realized I had installed netpbm-10.34 for the previous log, so here's one with netpbm-10.36.0.
The bug is in gocr's readpgm function. It passes a not cleaned struct pam to netpbm. I'll attach a patch to gocr-0.41 (please see bug 145624 for another necessary patch if you want to bump the version).
Created attachment 102438 [details, diff] Fixes calls to pbpamread in netpbm with dangling pointers
Patch for 0.41 has been submitted to & confirmed accepted by upstream.
Part the patch to api/src/image.c doesn't appear to have been applied to gogr 0.42. Unfortunately CVS commits for gogr appear to be being done in chunks prior to each release so not sure whether it is applied or not. Might also be dead code too.
Can you still reproduce this w/ 0.43?
(In reply to comment #18) > Can you still reproduce this w/ 0.43? No, I just tried and it appears to be fixed. I reproduced the original problem first (with gocr-0.40-r2) and then upgraded to gocr-0.43 which then ran successfully without segfaulting.
(In reply to comment #19) > > Can you still reproduce this w/ 0.43? > No, I just tried and it appears to be fixed. Fixed then, just needs to be stabilized.
*** Bug 183553 has been marked as a duplicate of this bug. ***
Doesn't go anywhere, CCing arches.
AMD64: already tested (bug 183553), feel free to commit
amd64 done, thanks Simon
x86 stable
ppc was already stable.
Everyone but alpha has this stable; can we close this bug? trying to clear my bug list ;)
