Mudflap crashes when it sees an accept in the form of:
accept(lsock, NULL, NULL)
and does not crash upon:
accept(lsock, &addr, &len);
The former case is - AFAIK - legal, quoting from the accept() manpage:
'When addr is NULL nothing is filled in.'
Attached is a minimal C program to reproduce this bug.
I tried this both on 4.0.0 and 4.0.1.
