Description

The environment is ppc64le/UBI 8.3 (RHEL 8.3 based container environment).

In fluent-bit application, luajit2 used as a filter and when creating lua context from application using luaL_newstate() function returns the value NULL instead of lua_state* pointer which causes issue.

This is inconsistent.
Sometimes luaL_newstate() function returns lua_state* pointer.
Sometimes function returns NULL pointer.

Tried on x86_64 for parity check, luaL_newstate() function returns lua_state* pointer always. No failures seen.

Any pointers help would be great.

Research direction

Start with the luaL_newstate() call in the fluent-bit application and compare behavior on ppc64le/UBI 8.3 with x86_64. Reproduce the intermittent NULL result and inspect the surrounding LuaJIT state-creation path. Done means identifying why ppc64le differs and verifying a consistent non-NULL result.
