> It appears that the destructor for this static string is being called twice
> by {{__run_exit_handlers}} and I don't know why. Anyone else seen this?
> For programs which are otherwise normal, this causes (nondeterministic)
> aborts on exit when glibc detects the double free. It might be specific to
> pyarrow, I haven't tried reproducing it with a C program that links with
> libarrow.so yet.
