          Hardware: Other

    Python Version: ---

A bug was filed in pkgsrc against mercurial 6.1: http://gnats.netbsd.org/56880

In short, please update the included zstd.

Here's the main content of the problem:


Cloning a repository with mercurial results in a bus error:

> Thread 1 "" received signal SIGBUS, Bus error.
> 0x7add40e0 in ZSTD_compressBlock_doubleFast ()
>    from /usr/pkg/lib/python3.9/site-packages/mercurial/zstd.so

This could be a known bug in zstd on this hardware:

https://github.com/RPi-Distro/repo/issues/179

The bug has been fixed in zstd 1.4.8, but the mercurial package
embeds the older version 1.4.4.
