------- Comment #2 from reichelt at gcc dot gnu dot org 2009-08-26 13:37 -------
Confirmed.
Shorter testcase (crashes with "-O -m32" on x86_64-unknown-linux-gnu):
==================================
int foo(volatile int i)
{
return (1LL >> 128 * i) && i;
}
==================================
The crash already occurs with GCC 4.4.0, but not with GCC 4.3.x.
