Full build log: https://dev.exherbo.org/~marv/1643879122-install-net-libs_webkit-2.34.4:4.0::gnome.out.nocolor

The last version I was able to build successfully on that system was 2.30.5, so I think it started failing with 2.32.x

Any idea what's going on here? Help is much appreciated

[Michael Catanzaro]

Works for me. Try adding:

#include "JITOpaqueByproducts.h"

in WasmLLIntPlan.cpp. Does that work?

[Marvin Schmidt]

Yep, that fixed it, thank you!
