Re: [PATCH]: Fix PR 3120


I get the same problem in the testsuite, lots of tests fail with:
FAIL: gcc.c-torture/compile/920617-1.c,  -O1  
Executing on host: /builds/gcc/gcc-3.1-devel/gcc/xgcc -B/builds/gcc/gcc-3.1-devel/gcc/  -w  -O2   -c  -o /builds/gcc/gcc-3.1-devel/gcc/testsuite/920617-1.o /cvs/gcc/gcc/testsuite/gcc.c-torture/compile/920617-1.c    (timeout = 300)

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

I'm not going to apply the patch in this form due to these regressions
on i686-linux.
