crash in ngx_add_timer

Hi, I am new to NGinx modules and I trying to write an nginx module. I am having an issue where my module crashes when adding multiple timers. The first timer adds fine. However, when I go to add the second timer, it crashes. I've simplified the code to a very basic module (which is attached to
