Compiling this invalid C++ code with current mainline:
void foo() { static int c = 2; static const char *a[][c] = { { "1", "2" } }; }
gives me:
foo.cc: In function ‘void foo()’:
foo.cc:1: internal compiler error: in tree_low_cst, at tree.c:4519
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
It should instead say something along the lines of
foo.cc:1: error: array bound is not an integer constant

------- Comment #2 from bangerth at dealii dot org 2006-09-28 05:59 -------
Confirmed. This actually worked in gcc2.95 to my surprise:
g/x> /home/bangerth/bin/gcc-2.95.3/bin/c++ -c x.cc
x.cc: In function `void foo()':
x.cc:1: variable-sized object of type `const char *[((c - 1) + 1)]' may not be
initialized
x.cc:1: storage size of `a' isn't constant
All later gcc versions ICE, however.
W.

------- Comment #3 from reichelt at gcc dot gnu dot org 2006-10-08 20:29 -------
Shorter testcase (the array doesn't have to be static):
=========================
void foo(int i)
{
int x[][i] = { 0 };
}
=========================
The bug appeared with GCC 3.3.
