>Description:
gdb-6.1, 6.3 crashes when 'call foo()' is executed and the exe was linked with xlC.
If the same object is linked with 'cc', no crash.
gdb-5.2 also works fine.
>How-To-Repeat:
$ cat junk.c
int foo() { return 0; }
int main() { return 0; }
$ cc -g -c junk.c
$ xlC -g junk.o ## if 'cc' is used here, gdb works fine
$ gdb-6.3 ./a.out
