Yes, it no longer ICEs. But this code seg faults:

#include <iostream>
int
main(int, char **)
{
    return 0;
}

Results from gdb 5.3:

warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0xa09f000000200
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable).  In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.

Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
