https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219692 --- Comment #4 from Jason Bacon <bacon4000@gmail.com> --- I would first check any assembly code that's wrapped in an SSE check. Maybe there's an instruction in there that's not implemented on older processors = that has nothing to do with SSE? SSE3 instructions should work fine on this processor. Do you know of an easy way to build with SSE *and* debugging symbols? If s= o, I can probably get GDB to pinpoint the problem. I tried just adding -g to CFLAGS, and it showed up when building with CMAKE_VERBOSE, but it didn't h= elp produce a good backtrace: Program terminated with signal SIGILL, Illegal instruction. #0 0x000000080275139a in thr_kill () from /lib/libc.so.7 [Current thread is 1 (LWP 100980)] (gdb) where #0 0x000000080275139a in thr_kill () from /lib/libc.so.7 #1 0x0000000802751386 in raise () from /lib/libc.so.7 #2 0x0000000801c623c6 in ??
