I have a feeling a recent plugin release is what has hosed things up.
Windows 10
Rack 1.1.6
Core I7-10700
32GB RAM.
Here’s the log.
I’ll log a problem on github for Rack, but this is almost certainly a module that is hosing up. I tried using c++filt to unmangle the point in the code where things got hosed, and for some reason it didn’t work.
