Hi,

FYI, with gcc trunk on x86_64 Linux, I ran into PR64042: 'FAIL:
boehm-gc.c/gctest.c -O2 execution test'. (
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64042 )

The testcase gctest fails spuriously, a couple of times per 1000 runs.

The failure has been reproduced by others, also on Darwin.

Any information on this is appreciated.

Thanks,
- Tom

I haven't had a chance to look at this carefully. But the typed allocation
test looks a bit fishy. It seems to allocate a 2000 byte object described
by a 320 bit entry bit map, each of which describes a pointer-sized word,
IIRC. That worked fine once upon a time when we this code was written and
we only had 32-bit machines ...
