Bug#1051900: ohcount: aborts with segfaul or bus error 90% of the time on arm64



Package: ohcount
Version: 4.0.0-3
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: debian-arm@lists.debian.org

Dear Maintainer,

ohcount segfaults (and sometimes aborts with a Bus error) on arm64,
almost 90% of the time. I tried this on an up to date arm64 Debian
testing against the hexchat source code, but it's also reproducible on
the ohcount source code itself. The same test, when performced on an up
to date amd64 Debian testing, finishes successfully 100% of the time.

For example this is a sample session with 10 runs against the source of
ohcount itself:

$ ohcount
Examining 1192 file(s)
Segmentation fault
$ ohcount

Bus error
$ ohcount
