When I tried to compile with -O5 -Dinline=__attribute__\(\(__always_inline__\)\)

Interestingly there's no inline word here, it must have been taken from some

The implementation of complex::pow can be definitely improved, and will, as soon
as Roger's work on signbit goes in, still, this issue seems limited to some very
specific, old version of hpux, pre release 11,

Yes, this test doesn't fail on hpux 11. This probably implies a
hpux 10 math library issue. I see the following math routines are
called log, atan2, exp, cos and sin in that order.
Indeed, I was thinking the

The part of the bug that produces the ICE (bus error) can be reproduced by
extracting and compiling all classes from a single jar. Unzip all classes from
SMOOD.jar by
unzip -l SMOOD.jar
and then compile with

We have log(x) == -inf for x == 0+. The exp call is returning 0+
but the argument isn't -inf. It's -5.9923104495410517e+307. -inf

Interesting. Therefore, 1/3*(-inf) instead of
1 - 100 of 121 matches
