I confirm. Bug #333766 was causing a SIGBUS in uic, when calling
feholdexcept. This has been fixed, and now the problem is a SIGILL that
occurs a few instructions later when calling __umoddi3 from
libgcc_s.so.2.
I have tried other version of libgcc2, from version 4.0.1-7 to version
4.1-0exp4, and the problem is always there. So it does not seems related
to a recent change in gcc. Maybe this part of code was never called
before for some strange reasons.
It would be nice if somebody fluent with hppa assembly can tell us if
fldw -10(,sp),fr23
is a valid instruction or not. If not, that's probably a miscompilation
in gcc, as this code is generated from C code.
