Not sure if it can be caused by this patch, but after rebuilding dbus with this gcc I got SIGILL while starting dbus-daemon --session on armv4t (om-gta02) Any hints? I'm leaving for weekend so not sure how often I'll be online or able to debug/test it. Program received signal SIGILL, Illegal instruction. 0x40041164 in utf8_encoding () from /usr/lib/libexpat.so.1 (gdb) back #0 0x40041164 in utf8_encoding () from /usr/lib/libexpat.so.1 #1 0x2a00789a in bus_config_parser_content () #2 0x400410f8 in features.3438 () from /usr/lib/libexpat.so.1 #3 0x400410f8 in features.3438 () from /usr/lib/libexpat.so.1 Backtrace stopped: previous frame identical to this frame (corrupt stack?)
