Crash when two pybind11 modules are imported #1562
Description
I don't think I can replicate this in a simple case, but I have two modules, each that operate just fine when they are the only module imported.
Builds are inside a conda environment, with visual studio 2015 64-bit as compiler. One package is this one: https://github.com/usnistgov/CEGO and the other one is an internal C++ library with a pybind11 wrapper.
When they are both imported, like so:
import PyCEGO
import VLEIsoTracer as vleI get a crash:

It seems like one library was built with commit 2bde615 and the other one was built with 51d18aa . When I sync both to master, there is no import crash. It seems like a bug that any modules compiled with pybind11 with two different commits result in a crash.

This was improved/fixed in #1012.
Meanwhile, the two commits you mention were not official releases, so you're it's not really a surprise that things don't cooperate well, then.
