Hi,
This is again a problem with -fnon-call-exceptions, a regression present on
the 3.3 branch and mainline.
Olivier Hainque proposed a patch two months ago
http://gcc.gnu.org/ml/gcc-patches/2003-07/msg01772.html
but it has not been applied yet because there is a controversy about the
following question:
Is it ok to delete a no-op insn that can trap?
It seems to me that this is a pretty fundamental question, so I'm a bit
astonished that there seems to be no clear position on the subject.
