Hi,

egcs-2.91.33 produces the following new FAILs:

FAIL: gcc.c-torture/execute/950511-1.c execution,  -O0
FAIL: gcc.c-torture/execute/950511-1.c execution,  -O1
FAIL: gcc.c-torture/execute/950511-1.c execution,  -O2

FAIL: gcc.c-torture/execute/950511-1.c execution,  -Os

objdump reveals the following strange code:
