LuaJIT also fix the 48VA issue by allocating heap memory below 47 bits.

For mozjs issue, if there are pointers to .rodata, it can be a problem. Does it happen on master and do we have any case to reproduce the issue so that I can take a look?

mozjs is fixed with your patch. I backported it to all of the ancient
versions of mozjs, so we're probably good there. Though every distro
will have to redo that work in their own trees, because older versions
of mozjs are no longer maintained upstream. If you want to be a hero,
you can try to port polkitd and gnome to use more recent versions of
mozjs ;). Or maybe they can already and we just messed up packaging.


I have a polkit built against mozjs45, getting it to work on the other hand is the yak of the day...
