Reproduces in a VM, it starts to fail with that commit. Looks like somehow
different macros are trampling on each other. Something in perl is interfering
with msvc's malloc.h, turning
if (_Marker == _ALLOCA_S_HEAP_MARKER)
{
free(_Memory);
}
into
if (_Marker == 0xDDDD)
{
(*(my_perl->IMem)->pFree)((my_perl->IMem), (_Memory));
}
after preprocessing. No idea how.
