Segfault with libmozjs even though emcascript is disabled

[Moult]

I just got this message - I have EMCAScript.enable set to 0:

ELinks crashed. That shouldn't happen. Please report this incident to
the developers. If you would like to help to debug the problem you just
uncovered, please keep the core you just got and send the developers
the output of 'bt' command entered inside of gdb (which you run as:
gdb elinks core). Thanks a lot for your cooperation!

Could you remind what your system is and how elinks was built: meson or configure options?

[Moult]

I do:

$ ./configure --with-python --enable-true-color --enable-256-colors --enable-gopher --enable-gemini --with-spidermonkey --with-libcurl
$ make

BTW I have no idea how to recreate this bug. It just happened and I thought it's safer to report in case it means something.
