Hi Colin (@colin-ada) . It's generally not recomended to clone the repo in the /mnt/x shares. Please clone the repo to the vhd if possible, for example, to ~. That should provide much better compilation performance and compatibility.

That said, I'm not able to repro your issue when having the repo on the p9 share, though the compilation is super slow.
