I think I'm actually hitting the same problem on x86 CPUs, but only some. I
can reproduce on `Intel(R) Xeon(R) Silver 4114` and `AMD EPYC 7V12` but not on
`AMD Ryzen 9 5950X`. It also requires a very obscure set of dependencies to
reproduce and I can reproduce on `pyarrow==17.0.0`, `pyarrow==18.0.0`,
`pyarrow==18.1.0` and `pyarrow==19.0.0`.
I'm fairly confident its the same issue because `gdb` looks almost the same
as the original report.

Building the wheel with `jemalloc` disabled solves the problem. I'm also
tempted to do a `git bisect` to try to determine exactly which commit started
this problem.
