Dear maintainer:
During an incremental rebuild of all packages in trixie, this package failed to
build:
=== RUN TestRegisteringHookMultipleTimesShouldBeSafe
promrus_test.go:103:
Error Trace:

panic: runtime error: invalid memory address or nil pointer dereference
[recovered]
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x40 pc=0x8a91ea]
That's what I got in my autobuilders, but it's also the way it fails in
reproducible-builds:
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/golang-github-weaveworks-promrus.html
I've decided to report this as "serious" because of the "invalid memory address or
nil pointer dereference", which seems, well, quite serious.
To reproduce, I usually build the packages using machines with 1 CPU and 2 CPUs,
and in this case I've noticed that it fails a lot more on systems with 1 CPU,
so maybe this is enough to reproduce it:
taskset -c 0 dpkg-buildpackage -uc -us
In case that would not be enough, please contact me privately, as I would
be willing to offer a virtual machine where this happens 100% of the time.
Thanks.
