           Summary: Simple dummy program fails with Segmentation Fault
                    upon -shared linking
           Product: gcc
           Version: 4.5.1
            Status: UNCONFIRMED
          Severity: normal

Here's my output of gcc -v:

I make a simple C program, compiled it an ran it. If I link it with -shared, it
segfaults, as in:

[Leo@chessman ~]$ cat test.c
int main(void) {
    return 0;
}
[Leo@chessman ~]$ gcc -c -o test.o test.c
[Leo@chessman ~]$ gcc -o test test.o
[Leo@chessman ~]$ ./test
[Leo@chessman ~]$ gcc -shared -o test test.o
[Leo@chessman ~]$ ./test
Segmentation fault (core dumped)
[Leo@chessman ~]$

I assume that this is a bug in collect2 and not cc1 given that linking
differently fixed it, but I would like to link with -shared so this is sort of
annoying.
