I use the latest packages and cygwin snapshots. The problem described

The following program, with static allocation of a reasonable amount
of data, segfaults, maybe in alloca(). With a smaller size
(eg 10000) it's ok. With new/malloc (even with 100 times more) it's
ok. With C or C++. 100% reproducible.
unsigned int const SIZE = 689471;
int foo[SIZE];
Reasonable? You're trying to stack-allocate 2.5MB of data. Don't do that
-- stack sizes are 2MB or less in most operating systems. Besides, doing
anything useful with a buffer that size would completely drown out the
overhead of calling malloc.
