gcc generates wrong code
command line: gcc -O2
works on: 3.4.4, 4.1.0-20050819
wrong code on: 4.0.1, 4.0.2-20050818
I am just guessing at the priority + severity levels.
Test program attached. It can be compiled and run standalone -- it succeeds
normally, and aborts if wrong-code is generated.
The wrong code is for the source line:
if (_v3 != _v4)
Where _v3 and _v4 are "const bool &".
