unprotected error in call to Lua API

[MarcusE1W]

Hi.

Today I tried to install luakit with Manjaro ARM an the PinebookPro
Unfortunately I get the same error with the provided package and installing from source when I start it the first time:

This is from the source code version:

[luakit]$ luakit -v

[    0.182785] E [core/common/util]: unprotected error in call to Lua API (bad light userdata pointer)

Any ideas?

Hi! Sorry for the slow response. Unfortunately this doesn't give too much information. The 'unprotected error in call to Lua API' message should be followed by a stack dump and a traceback, but these are missing, so there's really not much information to go on. :/

I get the same thing

Seems similar/related
LuaJIT/LuaJIT#245
kubernetes/ingress-nginx#2802

Don't know any lua, so unsure where to look, but I think luajit as a newer pointer type, and it's the light userdata pointer that doesn't seem to be compatible with aarch64?
