Testsuite regression, see:

The resulting executable fails it's own test on line 20 and calls abort().  With gdb, I see that the parameter p contains garbage:

(gdb) break check
Breakpoint 1 at 0x10001374: file execute/921117-1.c, line 9.
(gdb) run
Starting program: /caip/u58/ghazi/gcc-testing/egcc-CVS20020927/gcc/testsuite/gcc.c-torture/a.out

Breakpoint 1, check (p={text = "\0\0\0\0\0\0\0\089", flag = 0})
    at execute/921117-1.c:9
9         if (p.flag != 99)
(gdb) cont
Continuing.

Program received signal SIGABRT, Aborted.
