$ MOZCONFIG=~/src/dotfiles/moz/firefox.debug.mozconfig ./mach build

.... lots of stuff, successful build

$ ./mach mochitest-plain layout/base/tests/border_radius_hit_testing_iframe.html
Error running mach:

    ['mochitest-plain', 'layout/base/tests/border_radius_hit_testing_iframe.html']

The error occurred in the implementation of the invoked mach command.

This should never occur and is likely a bug in the implementation of that
command. Consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

mk_add_options AUTOCLOBBER=1
ac_add_options --enable-debug

ac_add_options --enable-application=browser

ac_add_options --enable-tests
ac_add_options --with-ccache

If I try running without mach I get

I bet if you run mach from the objdir without the MOZCONFIG environment variable set, it will just work.

Can you also paste the output of |mach environment| where you can repro this. If you are setting MOZCONFIG, please set that variable when running |mach environment|.

Ugh, this is my bad, I forgot to specify mozconfig when running mochitest-plain, annoying thing is I am fairly sure I have done this before, apologies
