While preparing the next upload of buildah 1.37.2 to Debian, I noticed build failures on s390x (and that arch only).

All build failures showed unusual behavior, (possibly indicating memory corruption?) in the test TestCheckLUKSPassphrase/v2 since version 1.37.0

Test output:

[...]

I wonder whether containers/luksy@dc16bfe would be related to this? the logs above depict builds with a copy of luksy that lack that commit.

I've just updated luksy to the most recent version in Debian and will update buildah to build against a copy of luksy with that patch.

nope, no difference, still seeing crash: https://buildd.debian.org/status/fetch.php?pkg=golang-github-containers-buildah&arch=s390x&ver=1.37.3%2Bds1-1&stamp=1727347791&raw=0

Was able to reproduce this quite easily on a s390x machine using a checkout of buildah (I used tag v1.37.7):

go test -race -gcflags="-d=checkptr" github.com/containers/buildah/internal/mkcw

I've pasted the output at https://gist.github.com/siretart/b6726406066ba1d80088edd19a133304
