At -O and higher with -fwrapv, svn 136854 improperly compiles func_9 below into
object code returning 0.
static unsigned long
mod_rhs (long int rhs)
{
return rhs;
}
unsigned g_8 = 0x0815898FL;
int func_9 (void)
{
return ((0x0274952FL * g_8) % mod_rhs (0x0274952FL));
}

I think this is related:
template struct A{};
template class B> struct C{};
int main() { C a; }
gives ICE @ pt.c:15861 (rev 136843).
The line in question is:

gfc_conv_array_parameter and maybe also gfc_trans_dummy_array_bias.

Better patch. I'm not sure whether we are ever freeing the memory, but I think
even if not, it is not a big problem.

This has now been broken for at least 3 releases and is going to stay broken in
