PR optimization/9786


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.
