[Bug c/15439] New: ICE with

[coyote at coyotegulch dot com]

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.

I think this is related to PR 19340.
