I have no bisect for this one because the test result is random:
sometimes OK, sometimes SEGV. I saw it the first time happen with
v5.17.6-281-g01f4497. The test script that triggered it was
t/010_internals/100_threads.t. I just ran the test with v5.17.6 a
hundred times without crash, so I suppose the problem stems from some
commit after that.
The stack trace:
This GDB was configured as "x86_64-linux-gnu".
