When using both out of process and in-process attachment, the host application crashes with:

This is using Qt 6.8.3 on Bazzite Linux.

Anything special I need to do to make this work?

[iamsergio]

Is it repro just by attaching Mudlet ?

Didn't manage to build: Mudlet/src/LuaInterface.cpp:696:29: error: ‘LUA_GLOBALSINDEX’ was not declared in this scope

Seems same object is being added twice

[vadi2]

Yep, just attach to Mudlet. You need Lua 5.1, not latest unfortunately.
