[Bug c++/23461] New: ICE in tree_low_cst, allocating oversized array from stack

[pete at void dot printf dot net]

The following is a minimal test case. Obviously, this is trying to do a dumb
thing, but it shouldn't give ICE, and g++ asked me to report it. The error is
"internal compiler error: in tree_low_cst, at tree.c:3843".

int main()
{
	int ptr[1000000000];
	return 0;
};

The output of g++ -v follows.

Using built-in specs.
