Hi,

This is a heads-up regarding the impact of Go 1.24, now available in
Fedora, and the subsequent mass-rebuild for Fedora 42. Over 200
packages are currently failing to build from source (FTBFS) [1] due to
a stricter check introduced in Go 1.24 [2].

The failure occurs due to a stricter vet check requiring non-constant
format strings to be explicitly handled. Affected builds fail with an
error like:

    non-constant format string in call to <function_name>

The failures typically occur during the %check phase, which is why
"source-only" packages are also affected.

Fixing this issue is relatively simple, and some patches have already
been submitted upstream [3][4]. However, addressing all affected
packages downstream will likely take several months.

Best regards,
Mikel
