>Description:
Gcc 3.0 crashes in template instantiation in:
gcc -o t t.C -O -g
t.C: In function `int main()':
t.C:15: Internal compiler error in emit_move_insn, at expr.c:2711
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
It is a regression because gcc 2.95.3 compiles correctly
the program (running the prog is ok too).
The crash seem to only occur with array types in the
instantiation (ie, char[12]).
