Package: libdispatch0 Severity: serious libdispatch0 uses SSE2 instructions ("MFENCE") which are not available on a Pentium 3.
According to http://www.debian.org/releases/stable/i386/ch02s01.html.en Pentium 3 has to be supported; so at least the user should get more than a "Illegal instruction" error message. Both stable and testing are affected (tested with forked-daapd from testing). gdb with version from stable: Program received signal SIGILL, Illegal instruction. 0xb6d4ef9c in dispatch_once_f () from /usr/lib/libdispatch.so.0 (gdb) bt #0 0xb6d4ef9c in dispatch_once_f () from /usr/lib/libdispatch.so.0 #1 0xb6d5021f in _dispatch_continuation_alloc_from_heap () from /usr/lib/libdispatch.so.0 #2 0xb6d4f621 in ??
