Philip,
The revised code works for me on gcc-3.2 as well, but not gcc-3.0. I
suspect this is a library difference (libstdc++-3 vs libstdc++-5),
though in principle I suppose it could be a compiler bug as well.
See bug 184242, which is this same problem applied to libstdc++-5.

With that code I get a crash when I use Debian's g++-3.0 version 1:3.0.4-7.
I also have a gcc-3.2 that I compiled from CVS
$ g++ -v

As Philip Martin pointed out in bug 185242, the testcase program
submitted is incorrect; having failed to return rval, the return value
is undefined in the case that rval != max.
Fixing this problem, I am unable to reproduce the bug on gcc-3.2 (though
still on gcc-3.0). New source code appears
Good point, though changing the function to return rval in the other
case seems to change the result not at all. I suspect that (due to luck)
rval is on the stack in any case.
Here is the modified code, with some additional checks:
#include
#include
#include
using namespace std;
using names
> unsigned int rand(unsigned int max) {
> unsigned int rval = (unsigned int)(((double)max)*rand()/(RAND_MAX));
> if (rval == max)
> return max-1;

This function returns no value if rval != max so the behaviour is
undefined.
