Hi Giovanni,
Just to add another data-point: It also breaks on Visual Studio (tested 2017
and 2019-preview), not just GCC.
Thanks you for the pointers on the ABI, very interesting.
At the purely-C level, without looking under the hood, if a compiler returns
sizeof(_Bool) == 1 (which TCC does at least in my i386 tests), wouldn't it be
internally inconsistent to test a _Bool return value for 4 bytes being 0 as
opposed to just 1?
Thanks,
Louis
