Old Synopsis: #243 gcc2.96 - template problems
New Synopsis: SegFault with deducting template args from variably sized arrays
State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Fri Jan 10 17:24:09 2003
State-Changed-Why:
I doubt this is legal, but it shouldn't segfault either.
In any case, this still happens even with present 3.4, as
well as with all other versions in between.
Testcase:
---------------------------
template <int H, int W>
void function(int (&wmarker)[H][W]) {};
void method() {
int h=1, w=2;
int array[h][w];
function(array);
}
