Steps to reproduce:

I tried to compile spidermonkey-78.4.0 for armv7a-unknown-linux-gnueabihf using clang

Actual results:

the build fails with a fatal error when compiling mozglue-static 0.1.0:

full build log is attached

Expected results:

the build passes fine when using gcc with armv7a-unknown-linux-gnueabihf

aarch64-unknown-linux-gnu passes with clang and gcc, so it's not affected

this is a really confusing bug, because I can't even see from where this error is actually from. Since it only backtracks to the build dir, I'm already lost at finding the correct lines in the source code from the firefox-78.4 source tarball.

Hi,

I will move this over to a component so developers can take a look over it. If this is not the correct component please feel free to change it to an appropriate one.

Thanks.

Looks like this report got lost in the system, sorry about that.
Since it's so old I'm going to close this report. Feel free to reopen if it's still relevant.
