Hi,
I tried to profile an applications but there's a problem - the
application crashes in getopt(). I've constructed a simple test case
that demonstrates this:
--- foo.c --
#include <getopt.h>
int main(int argc, char **argv)
{
getopt(argc, argv, "h");
return 0;
}
------------
> gcc -pg -g -o foo foo.c
> ./foo
Segmentation fault (core dumped)
> gdb ./foo foo.core

The same test case works on a 6.x machine. Am I missing something or is
profiling broken?
