gcc 4.2 profiling breaks argv

Hi all,

Programs segfault when attempting to access argv from main when compiled 
under gcc 4.2.0 with the -pg profiling option.  The following program 
illustrates this problem.

$ cat test.c
#include <stdio.h>
int main (int argc, char **argv) {
   fprintf (stderr, "argv=%p\n", argv);
   return 0;
}
$ cc -c -o test.o -pg  test.c  &&  cc -o test  -pg  test.o
$ ./test
Segmentation fault (core dumped)

$ cc -v
Using built-in specs.
Target: i386-undermydesk-freebsd
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 4.2.0 20070514 [FreeBSD]

This issue was reported on this list on 5th July 2007 by Garrett Cooper 
but argv was not mentioned in that post.  I have not seen this problem 
reported elsewhere (e.g. on the gcc mailing list).
