[Debian-med-packaging] Bug#1112654: mosdepth: FTBFS: /usr/share/nimble/regex/regex.nim(859, 18) Error: Exception can raise an unlisted exception: Exception

[Santiago Vila]

Package: src:mosdepth
Version: 0.3.10+ds-1
Severity: serious
Tags: ftbfs forky sid

Dear maintainer:

During a rebuild of all packages in unstable, your package failed to build.

Note: All the following packages also FTBFS, if you happen to have a fix for any of them
maybe you can also fix some of the others:

src:hts-nim-tools
src:mosdepth
src:nim-hts
src:nim-lapper
src:nim-regex

Below you will find how the build ends (probably the most relevant part,
but not necessarily). If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202508/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:mosdepth, so that this is still
visible in the BTS web page for this package.

Thanks.
