FYI, the giveback build (on a different host) didn't crash: https://buildd.debian.org/status/fetch.php?pkg=gitsign&arch=mips64el&ver=0.13.0-1&stamp=1744439515&raw=0
It could be that some build dependency changed version between these runs (comparing the build logs is a bit messy), or some temporary problem on the first build host. Anyway until it happens again I think we can ignore this problem, unless someone wants to analyze the backtrace further and try to reproduce it. /Simon Simon Josefsson <si...@josefsson.org> writes: > All, > > I got a SIGSEGV from running 'go test' on mips64el in gitsign.
