(to be clear, don't need distclean to reproduce this, I just did it as a hack because I can only hit it rarely with `./configure && make`.)
Created attachment 850126 [details] build with MAKEOPTS="-d --shuffle=1146935951 -j32"
Note that there's two bugs: 1. The race condition 2. mkscan.sh doesn't fail when the pipeline fails, and nothing notices it fails either, so a corrupted scan.o is generated with barely any contents, the failure happens later on when linking goes wrong: ``` $ nm scan.o 0000000000000000 n wm4.0.e19e8bb94d9c36428d25f5949bc3e9e0 0000000000000000 n wm4.stdcpredef.h.19.88fdbfd5cf6f83ed579effc3e425f09b ``` Arsen took a look and thinks the scan target should use initscan unless flex exists & is executable.
