Hello,

this must be a few days old at maximum.  Random example:

Byte compile a file containing

  (set '#:my-toggle-invisible 3)

Load the compiled file ==> (wrong-type-argument symbolp (nil))

Interpreted code works.

CC'ing Alan because this might be related to his latest changes to the
compiler, I didn't investigate, sorry if not.


TIA,

Michael.

Thanks!  A bit of bisecting shows that the bug was introduced by the
following commit:

commit 6092ee1c3ff503fbe8087e13b7eae2f904c4af3b
Author: Alan Mackenzie <acm <at> muc.de>
Date:   Thu Feb 24 17:30:39 2022 +0000

    Amend byte-run-strip-symbol-positions so that an unexec build builds

..  I'll have a look at this and see if I can work out how this commit
causes the bug.

Yes, it was a bug in the byte compiler I introduced recently.  I've just
committed a fix.  Could you please update your repository, and let me
know whether this fix fixes the bug fully.  Thanks!

Could you also let me know whether this fix has any positive impact on
the other bug, #54079.  Thanks again!

Looks good, I don't see this issue any more.

I don't see any impact unfortunately, that issue looks unchanged.

Anyway, thanks for fixing this one, I'm just closing it...

Michael.
