It seems like maybe some state must be left behind and affecting the second run.

Is there a command line option to run the test twice or how are you running it twice in one session?

FWIW, I tried just duplicating the two self.btest_exit lines multiple times and it seems to run fine.

Hmm.. I as able to repro the other day, and I've seen in in the CI.. but I'm not sure if it consistent. I'll try again now..

I'm seeing this issue on some CI runs. e.g.: https://app.circleci.com/pipelines/github/emscripten-core/emscripten/34717/workflows/01f23013-b724-4ec3-81b3-33a49727d0ab/jobs/775610
