I don't think this is a problem in cbindgen. > The futex facility returned an unexpected error code. Sounds like something is wrong with your system. Are you able to reproduce?
(In reply to Thomas Deutschmann from comment #7) > Sounds like something is wrong with your system. Are you able to reproduce? Hhm, it emerges now fine at all images - even at this image. By any chance a make -j3 issue ?
I don't know. I cannot reproduce even with RUSTFLAGS="-Ccodegen-units=3".
I agree, something specific to the system it seems. I've found codepath returning futex error, it's in glibc see https://bugs.gentoo.org/799878#c8
