I suspect you have a corrupt or otherwise incorrect font file in your Windows fontdir. What happens if you remove that directory from /etc/fonts/fonts.conf? Can you try to narrow it down further to a specific font file? Yes, that was it. The Thai font Angsana New (Regular) was corrupt; removing it and all the other Angsana TTF files fixed that problem. Now I'm back to debugging, on the Vista machine where gdb actually works [1], the original problem with rxvt-unicode which I encountered on W7 -- that is, whenever I do anything interesting (like, say, simply starting vi), my rxvt-unicode terminal crashes with a SIGABRT: Program received signal SIGABRT, Aborted. 0x in ??

() No idea why. I have debugging symbols available but...the abort appears to occur down in ntdll somewhere, and I have nothing informative in the remaining backtrace. Sigh. I'm pretty much stumped at this point; my next try will be to build a completely minimal, zero frills, version and see if it works better. If so, then slowly add features back...

coredumps with fc-cache, fc-list
While trying to debug the problem with my new build of rxvt-unicode, I find that I am getting a segfault way down deep in libfreetype. I rebuilt libfreetype with the new cygport, so I could get those handy debug symbols, and spent some time trudging thru that. Then, since libfreetype is actually called by libfontconfig, and not directly by rxvt-unicode, I decided to download the -src package and rebuild THAT, too -- again, so I could have debug symbols for a few of my intervening stack frames. The (re)build of fontconfig-2.8.0-2 went fine, but when setup installed it, I got an error during postinstall. Setup.log.full says: 2012/08/28 01:38:48 running: C:\cygwin-1.7\bin\bash.exe --norc --noprofile /etc/postinstall/fontconfig.sh /etc/postinstall/fontconfig.sh: line 2: 4164 Segmentation fault (core dumped) /usr/bin/fc-cache -r Ick. So, I reinstalled the real version...and I got the same message: 2012/08/28 01:53:01 running: C:\cygwin-1.7\bin\bash.exe --norc --noprofile /etc/postinstall/fontconfig.sh /etc/postinstall/fontconfig.sh: line 2: 6856 Segmentation fault (core dumped) /usr/bin/fc-cache -r Running 'fc-list : family' also coredumps (using the official fontconfig-2.8.0-2). *=-=-=-=-=-=-=-=-=* I next ran 'fc-cache -fsv' as Adminstrator, and everything went swimmingly...until I got to the Windows dir: ... /usr/share/texmf-dist/fonts/type1/urw/times: caching, new cache contents: 4 fonts, 0 dirs /usr/share/texmf-dist/fonts/type1/urw/zapfchan: caching, new cache contents: 1 fonts, 0 dirs /usr/share/texmf-dist/fonts/type1/urw/zapfding: caching, new cache contents: 1 fonts, 0 dirs /cygdrive/c/Windows/Fonts: Segmentation fault (core dumped) FWIW, I have 469 true type fonts in Windows/Fonts.

Any ideas? I'm going to try, just for grins and giggles, installing a self-built version of fontconfig-2.10.$latest and see if that helps matters...but I won't be able to do so until Thursday at the earliest. -- Chuck -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
