https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D246630 --- Comment #21 from Fabian Keil <fk@fabiankeil.de> --- Building r360524 with CLANG_SPAWN_CC1=3D1 resulted in unreproducible /bin/sh binaries which is unsurprising if the variable is no longer read by clang. Surprising is that I also built systems based on r361652 (stable/11 from 2020-05-30) on a 4-core system and a 2-core system, once per system with CLANG_SPAWN_CC1=3D1 and once without, and only got reproducible rescue bina= ries with the variable set. I confirmed that there is no code left that is reading the variable so it s= eems like the issue isn't triggered 100% reliably. This would also explain why I didn't see it with the FreeBSD-13.0-CURRENT 20200514-r361019 snapshot even though you are seeing it on HEAD. I'll test the lib/clang/include/clang/Config/config.h modification next. Setting it permanently wouldn't be a problem for ElectroBSD. --=20 You are receiving this mail because: You are the assignee for the bug.=
