Relevant part of the log:
/var/tmp/paludis/build/net-www-firefox-58.0.2/work/build/dist/include/mozilla/Compiler.h:49:12: fatal error: 'cstddef' file not found
thread '<unnamed>' panicked at 'Failed to generate bindings, (...)'

This kind of rings a bell. Nathan, weren't you involved in something similar?

Comment 2

[Nathan Froyd [:froydnj]]

I was, but the usual platform where we saw this was Mac, and I think the build log is from Linux (Gentoo?).

Is there anything peculiar about where Gentoo stores its libstdc++ (libc++?) headers, and would the clang in use (presumably /usr/bin/clang, as returned by /usr/bin/llvm-config) normally have trouble finding those?

Comment 3

[Nathan Froyd [:froydnj]]

Also, this is the second or third report we've had about Rust 1.24 doing weird things (see bug 1439278), so:

1) How does Gentoo build Rust? and
2) Does the problem reproduce on Gentoo if you use upstream's build of Rust instead of Gentoo's build?

[Nathan Froyd [:froydnj]]

It looks like this was a problem specific to Rust 1.24 and the way distributions built it.
