Issue #14948 has been updated by k0kubun (Takashi Kokubun).

> Starting with r64076, every subsequent build has failed

Does this mean, 64075 passes and r64076 fails? r64076 changes almost no behavior, so I feel it's very unlikely that r64076 is related to the failure.

2 points to notice:

* I fixed memory leak on r64075 but it had a bug of double free. The SEGV-ing bug, which is probably hard to be caught in test_jit.rb, was fixed on r64082 but it seems not related to your failure because your output includes r64082.
* Recently I added a new test to increase test coverage in r64072. I guess the mingw build started to fail on that commit and probably unload_units on mingw has never worked. I'll take a look later.

----------------------------------------
Starting with r64076, every subsequent build has failed, both in parallel & retry, on `TestJIT#test_unload_units`.

Finally ran it locally, below is the log of running the whole test file/suite.

Thanks again, Greg
