If you want to run `kill 0', which sends SIGTERM, from a SIGTERM trap handler, you need to reset the SIGTERM trap to the default before doing so. Bash allows recursive trap handlers. What's happening is you're recursively invoking the trap handler until you exceed the stack space resource limit. Bash has an internal limit on how many times you can recursively eval a trap handler, but you run out of stack space before exceeding it.Ok.

Because this is a feature that was added between 2007 and now. Bash-3.2
didn't allow recursive trap handler invocations.
