--- Comment #3 from John F. Carr <jfc@mit.edu> ---
I can confirm this running native stable/13 on Ampere eMAG and current on
Cortex A-57. The program sometimes hangs.
Running in a debugger I get occasional addressing errors (segfault or bad
address). I think the errors are caused by a bad interaction between lldb and
system calls. Conceivably it is a scheduling problem that only shows up with a
debugger.
