Frank,
How did you think it's calling pthread_mutex_lock(NULL), but no other e.g.
pthread_mutex_lock(invalid address, e.g. 0xf)?
I think the NULL pointer into pthread_mutex_lock is not accordant with signal
SEGV (access to address exceeded protections).
BR,
Eric

How to print string in C++:
e.g. string Fun(string a, int b)
Then I'll try to printf the return value of this Fun().
*:return
{
printf(ret = %s, stringof(arg0));
...
}
But DTrace told that this use is uncorrect.
Then how to get the return string value??
