All, I got a SIGSEGV from running 'go test' on mips64el in gitsign. Does anyone understand any of the backtrace below? Has anyone seen this for any other Go packages? Buildd log here:
https://buildd.debian.org/status/fetch.php?pkg=gitsign&arch=mips64el&ver=0.13.0-1&stamp=1744282800&raw=0 I've asked for a giveback so we can learn if this was a spurious crash or happens more than once, but the mips64el buildd seems busy. Which package would be the right one to file a crash like this on? golang-1.24-go? /Simon dh_auto_test -a -O--builddirectory=_build -O--buildsystem=golang cd _build && go test -vet=off -v -p 4
