<pre>When I try this on MacOS:
llvm-stress -seed=1659519802 -size=700
The program hangs. It appears a bug was introduced in change 295325.
Specifically, operator()() returns a 32 bit number, but it's not supposed to
return anything larger than max(), which is 0x7ffff:
uint32_t operator()() { return Rand32(); }
static constexpr result_type min() { return 0; }
static constexpr result_type max() { return 0x7ffff; }
Changing it to this:
uint32_t operator()() { return Rand32() % max(); }
Causes it to work properly.</pre>
