gcc profiling broken?

A simple program like this:

#include <stdio.h>

int main(int argc, char* argv[])
{
    printf("Hello, world!\n");

    printf("argc: %d\n", argc);

    return 0;
}

when compiled with profiling:

 gcc -pg -g hello.c -o hello

dumps core:

Starting program: /home/andrew/dev/kmv/components/tests/prof/cee/hello
Hello, world!

Program received signal SIGSEGV, Segmentation fault.
main (argc=Error accessing memory address 0x19: Bad address.
) at hello.c:7
7           printf("argc: %d\n", argc);


I run i386 7 beta1 from yesterday.

gcc -v
Using built-in specs.
Target: i386-undermydesk-freebsd
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 4.2.1 20070719  [FreeBSD]
