As the initial reason of this bug is solved, I close it. In fact is the
__chkstk function here incompatible to VC version, but this should be part of a
feature request.

And just think of the havoc that will be caused with old mingw32 and cygwin
libs that depend on the _chkstk meaning of __alloca if you change __alloca
semantics.
eg there are 69 undefined references to

I agree, that the havoc for 32-bit backward compatibility is to avoid.
But the havoc for windows sources using -fno-builtin and using _alloca () for
stack allocation produces in future even more troubles IMHO.

void *_alloca (size_t size) {return __builtin_alloca (size));
Ugh.

Why? it has been a bug in GCC for a while now. And x86_64-pc-mingw32 is new.

Actually, I see this as unfortunate choice of name for the undocumented
__alloca label rather than as a serious bug.
__alloca is an internal symbol that should have been named _alloca_probe for
