Did the test machine you used actually have that many cores?
No idea
I tried building with SMT off (so the machine only has 20 visible
cores). I could reproduce the failure. (I disabled SMT at runtime using
ppc64_cpu --smt=off)
It also fails when running 'make check VERBOSE=1' (so it's not caused by
parallelism).
It crashes with:
(gdb) r -o /tmp/tmp.k64Np1I2cr -n 10 -r -p
