Created attachment 794123 [details] ps faux Noticed when building glibc-9999 (just before glibc-2.36) (at commit https://sourceware.org/git/?p=glibc.git;a=commit;h=ca4d3ea5130d66e66c5af14e958e99341bf20689), but I think I hit this when trying to test build just before glibc-2.35 was cut.

Oh, duh, it's not as. It's GCC. It just spawns an `as` (which waits a looong time for input) if using -pipe.
Nothing for us to do here really.
