It has been committed: gcc+glibc will now warn if a user uses a NULL argv array in an execv* call or a NULL argv[0] in an execl* call. But the gcc warnings can cover only 7 out of 11 cases. Therefore the kernel behaviour is more important. Is there anyone who could help out and test the proposed Linux kernel patch? Bruno
