Ugh, SPARC; could be a miscompilation issue, since that's yet another
platform that gcc is usually completely untested on.  It's slow
because the CPU is extremely slow, of course.  Doesn't help that
there's almost no asm for it either (and you didn't compile whatever
little there was).

Can you post a backtrace with line numbers?  Without line numbers it's
a bit hard to debug anything.  I'd suggest using --enable-debug and
then adding back the optimization flags that resulted in the crash.
