https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63684 --- Comment #15 from Phil Muldoon --- Can you try building out of tree to see if it fixes your case? IE: mkdir obj cd obj ../trunk/configure . (replace trunk with the source directory if you are using git)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63684 --- Comment #14 from Jakub Jelinek --- That is weird, because actually the objdir subdir of srcdir case is what works fine and is daily tested, and objdir == srcdir case is the problematic case that often doesn't work.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63684 --- Comment #11 from Sasha Levin --- That's correct. I'm just building in-tree and using 'git clean -df' to reset everything back to a pristine checkout state when I need to.
