Yes, the parallel builds of glibc you described crashed the unpatched host 100% reliably for me. I also have a standalone reproducer I'll send you. > If the unpatched host crashes for you but the patched doesn't, I will > make sure I didn't accidentally miss anything.

I tested upstream stable v5.14.13 + my patches, but there's nothing betwen 5.14.12 and 5.14.13 that should matter AFAICS. > Let me do some more testing. Thanks. cheers
