The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202412/

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 affects, so that this is still visible in the BTS web
page for this package.

Thanks.

Hi. It seems golang-goptlib changed namespace between upstream
releases, and snowflake has to adapt. However, it is possible to solve
this with a hack in golang-goptlib, so I did that.

thank you so much!

btw, you might want to look into:

https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40105#note_3139337

and more specifically:

https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40410#note_3139364

since we still need to figure out exactly how to ship the latest
snowflake upstream here. your help would be greatly appreciated!
