The plmerge binary segfaults during emerge of GNUstep packages, with gnustep-base/gnustep-base-1.24.6-r1, sys-devel/clang-3.5.0-r100 and gnustep-base/libobjc2-1.7, when gnustep-base is built with -march=pentium4/native -O2. This bug doesn't occur when -march=pentium4 -O1 or -march=i686 -O2 is used. I noticed these plmerge segfaults earlier using clang-3.4.2-r100. Maybe a compiler bug? Only in a few cases the plmerge segfaults cause the emerge process to die. Most of the time though, emerge finishes "successfully" and a core dump is dropped. From the packages I use, these abort their emerge: gnustep-back-cairo-0.24.0, systempreferences-1.2.0, highlighterkit-0.1.3 and gworkspace-0.9.2. I can lookup the packages that continue despite plmerge segfaults, by comparing the time of the core dumps with /var/log/emerge.log, if that's useful info. :) All core dumps look the same, so I'll attach one as an example. An example of the build.log etc. (including the error) can be seen here: https://bugs.gentoo.org/show_bug.cgi?id=366795#c28 (...) if [ -r "libgnustep-back-024Info.plist" ]; then \ plmerge libgnustep-back-024.bundle/Resources/Info-gnustep.plist libgnustep-back-024Info.plist; \ fi /bin/sh: line 2: 28626 Segmentation fault plmerge libgnustep-back-024.bundle/Resources/Info-gnustep.plist libgnustep-back-024Info.plist make[3]: *** [libgnustep-back-024.bundle/Resources/Info-gnustep.plist] Error 139 make[3]: *** Deleting file `libgnustep-back-024.bundle/Resources/Info-gnustep.plist' make[2]: *** [libgnustep-back-024.all.bundle.variables] Error 2 make[1]: *** [internal-all] Error 2 make[1]: Leaving directory `/var/temp/portage/gnustep-base/gnustep-back-cairo-0.24.0/work/gnustep-back-0.24.0/Source' make: *** [internal-all] Error 2 (...)

Cleaning old bugreports, I think this has been fixed for some time with some newer components (probably clang). Though if it still fails with current packages, don't hesitate to reopen
