Hi Ben, yes, I see the bug. The problem is with import of PNG images with alpha channel. I tried to cut out the alpha channel and I no longer face the segfault problem. So you can use it as a simple workaround now. I'm now figuring out the reason for the segfault. thanks, Jindrich Jindrich, thank you so much for taking the time to look at this. I worried it wouldn't get much attention since pdflatex is a bit obscure. pdflatex doesn't do anything useful with alpha channels anyway, at least not yet. The workaround you suggest will be easy to enact and will get me back up and running (or at least typesetting) quickly. Thanks again! Ben, I found the reason why pdflatex segfaults. It looks like the problem is not in pdflatex but libpng. The pdflatex segfaults only with libpng-1.2.7. To fix this please downgrade to libpng-1.2.2, where this error doesn't occur. (tested) You can get working libpng from: http://sunsite.mff.cuni.cz/pub/fedora/2/i386/os/Fedora/RPMS/libpng-1.2.2-22.i386.rpm I'll file a bug against libpng so hopefully this will be solved soon. greetings, Jindrich The new release of libpng-1.2.8 fixes the issue. Fix confirmed in libpng-1.2.8-1.fc3. Thanks, Jindrich! |
