>Description:
Modified gcc.c-torture/execute/loop-2c.c test case fails on i586-pc-linux-gnu when compiling w/ -Os.  I actually noticed this problem on the 3.1 branch, but I think the mainline is also affected...  I'll verify this and post a patch.
>How-To-Repeat:
gcc -Os loop-2c-new.c
./a.out
>Fix:
patch pending...
