Hello, the calls test fails in Lua 5.4 on big endian platforms (ppc64, s390x), please see https://bugzilla.redhat.com/show_bug.cgi?id=2226537 for the original report. I suppose it is because the precompiled code added in https://github.com/lua/lua/commit/ab859fe59b464a038a45552921cb2b23892343af is from a little endian system (eg. x86) and is platform specific, thus it won't load correctly on a big endian system. Is there a way how to fix it? Thanks, Dan
