That's a good choice.

I still don't get why a custom signal handler is needed:

man assert: `assert() ... terminates the program by calling abort(3)`

man abort: raises SIGABRT, but `If the SIGABRT signal is ignored, or caught by a handler that returns, the abort() function will still terminate the process. It does this by  restoring  the default disposition for SIGABRT and then raising the signal for a second time.`

This is POSIX behavior. If glibc doesn't behave like this, it is a bug. If it does, I don't understand why the code sets a variable in a signal handler. A check after a failed assert() doesn't make sense (except as a work-around for buggy glibc behavior).
