Bug#1004048: golang-github-komkom-toml: autopkgtest regression on armhf/i386: -{"hex3":3735928559}, +{"hex3":-559038737}

[Paul Gevers <elbrus@debian.org>]

Source: golang-github-komkom-toml
Version: 0.0~git20211215.3c8ee9d-1
X-Debbugs-CC: debian-ci@lists.debian.org
Severity: serious
User: debian-ci@lists.debian.org
Usertags: regression

Dear maintainer(s),

With a recent upload of golang-github-komkom-toml the autopkgtest of 
golang-github-komkom-toml fails in testing when that autopkgtest is run 
with the binary packages of golang-github-komkom-toml from unstable on 
armhf and i386. It passes when run with only packages from testing. In 
tabular form:

                          pass            fail
golang-github-komkom-toml from testing    0.0~git20211215.3c8ee9d-1
all others                from testing    from testing

I copied some of the output at the bottom of this report. Seems like a 
32 bit issue where some value overflows.

Currently this regression is blocking the migration to testing [1]. Can 
you please investigate the situation and fix it?
