Segfault in InternalCallOrConstruct when using pmjs event-loop #112
Description
PythonMonkey Version: 68dca85
Repro: ./pmjs tests/js/timers-segfault.simple.failing
Note that I am using the node-style event-loop events implemented in Python, not the standards-compliant ones implemented in C++
This problem is probably not related to the events code, but rather, the events code is setting up a bug in PythonMonkey.
