This bug is tracking the discussion from https://github.com/mono/mono/pull/3369
The summary is that a TAE landing in a .cctor should be routed around and keep the type viable.
Right now the TAE lands straight in the middle of the .cctor, punch it in the face, ruins the type and sneaks out hidden in a TLE.
It seems like this is a regression.
It's not a regression per-se. The wrong behavior always existed, but became much more problematic with Zoltan's change to switch thread stop to abort instead.
We discussed back then that we'd need to get this and Kyte's fix in.
Merged, let's hope it works.
We are still seeing this, for example
We did another round of fixing around the cctor abort January 2017: https://github.com/mono/mono/pull/4274
CC'ing Vlad as he recently did some work on interruption - changed how finally guarding is done.
