When compiled with
gcc -O1 -c -fschedule-insns2 -fsched2-use-traces bug_reg_stack.c
the attached program generates:
bug_reg_stack.c: In function `molebench':
bug_reg_stack.c:26: internal compiler error: in convert_regs_1, at
reg-stack.c:2950
Changing the array size from a static const to a literal int eliminates the ICE.
Removing the return value (and changing the function type to void) also
eliminates the ICE.

Steven confirmed this on 3.4, but it looks "fixed" on mainline 20041004.
Probably, it means that the bug is papered over. Honza promised to have a look
at this, so I'm assigning this bug to him.
Notice, this is not a regression, since it is caused by -fsched2-use-traces
which did not exist in 3.3.
