Endless llvm emit object

I run into an endless LLVM Emit Object when building on linux. On windows it takes 40 seconds but it is compiling correctly. I tested linux with a windows WSL2. I suspect the use of @embedFile builtin as a long llvm emit object happens when the file is rather small (diff) to in fine being infinite (tested for 15 minutes) for this diff with a bigger file. Couln’t find anyone complaining about this on the forum. Is there a known bug? (Using zig 0.16.0)
