Steps to reproduce:

git clone https://github.com/broadwaylamb/OpenCombine.git
cd OpenCombine
git checkout 03172ff14c4b135315da1aa95a6cffcb73bec8e8
make test-release

This commit fixes the crash. I don't know why, I figured it out using git-bisect.

I tried to reduce the test case, but no success, sorry 🙁
