OK, this is the problem: _Jv_RegisterClasses shouldn't be passed NULL.
It's called from frame_dummy() and __do_global_ctors_1() in
crtstuff.c:
#ifdef JCR_SECTION_NAME
if (__JCR_LIST__[0])
{
void (*register_classes) (void *) = _Jv_RegisterClasses;
__asm ("" : "+r" (register_classes));
if (register_classes)
register_classes (__JCR_LIST__);
}
#endif /* JCR_SECTION_NAME */
OK, now here is the real weirdness: gcj-dbtool is *used* during the
RPM build, so that exact same gcj-dbtool binary that is now
segfaulting must have worked once.

OK, so this address indicates that we're being called from the main
program, not while initializing a library.
Maybe something has broken /lib/ld-linux.so.2. I'll try updating;
here goes.
Andrew.
