These are different mechanisms to execute cleanup functions. You can
have both executing the same function, as long as it checks the state
and performs nop (no operations) if the cleanup had already been done.

I guess because SIGSEGV is delivered to the process before that function
had a chance to execute? They don't run in parallel at the same time, so
when atexit handler runs first, it crashes the process.
