On amd64 systems with <sys-devel/gcc-4.7, tumblerd segfaults before loading/creating thumbnails. Steps to reproduce: 1. emerge =xfce-extra/tumbler-0.1.27 2. Open a directory which contains files need thumbnails by Thunar (or ristretto). Actual results: /usr/lib64/tumbler/tumblerd segfaults. Backtrace is follow. (gdb) run Starting program: /usr/lib64/tumbler-1/tumblerd warning: Could not load shared library symbols for linux-vdso.so.1. Do you need "set solib-search-path" or "set sysroot"?

Notes: * Segfault could not be reproducible on x86(32bit), occurs only on amd64(x86_64). (but not sufficiently tested on x86 because my x86 box is very slow...) * Segfault could not be reproducible if I reduced gcc optimization. CFLAGS="-O0" is fine, no segfault and tumblerd seems to work properly. CFLAGS="-O{1,2,3,s}" causes segfault. * Segfault could not be reproducible with >=sys-devel/gcc-4.7.0. I tested with gentoo's gcc (i.e. without USE="vanilla"). gcc-{4.3.6-r1, 4.4.7, 4.5.4, 4.6.3}: segfault occurs. gcc-4.7.0 and gcc-4.7.2: segfault doesn't occur. (and with sys-devel/clang-3.1-r5: segfault doesn't occur) * The issue is since upstream commit 8913e999caed579d62b0021f32db6dfef65ff7f4 "Add config file system to control thumbnailing plugin." http://git.xfce.org/xfce/tumbler/commit/?id=8913e999caed579d62b0021f32db6dfef65ff7f4
