Quoting Wouter van Gulik <address@hidden>:

Do you have a clue on why the tests fail? There is an ugly bug concerning
stack allocation and 64 bit variables, maybe that is the evil one. See:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27386 for details.

All the failed tests I've seen so far do in fact pass "long long" arguments to functions together with a bunch of other arguments (sometimes using va_args, too).

In one of the cases (gcc.c-torture/execute/20030307-1.c), the test only fails at -O0 and -O1, but passes with other optimization levels because the functions get inlined and disappear completely, so the argument passing problem disappears too.

So, I would say that it is very likely the same bug...
