Oh, and to add, if you change the double to an int, it works.

I should point out that fixing the actual bug in question will fix the ICE
itself.

Fixed in 3.4.0 and above. 3.3.x is only gcc releases which are effected so
closing as fixed as 3.3.6 was
the last release of 3.3.

Using gcc --version:
g++ (GCC) 4.1.0 20050607 (experimental)
I still cannot get anything using the -ftrapv:
Ex is:
#include iostream
int main()
{
const unsigned int a = 11;
const unsigned int b = 10;

(In reply to comment #6)
It looks like -ftrapv only works on signed overflow.
Yes because signed overflow is undefined. unsigned overflow wraps by both the

I can still reproduce the same unsafe operation:
#include iostream
int main()

unsigned int l = (unsigned int)-1;
const int a = l/2;

The GCC 4.0.0 documentation, page 71 in the PostScript version,

Perform dead code elimination (DCE) on trees. This flag is enabled by default
