max-specpdl-size mysterium with nXhtml

max-specpdl-size mysterium with nXhtml

[Lennart Borgman]

I have got a bug report that I do not understand at all and would
appreciate any help and thoughts. Chris, a user, gets an error when he
opens a file with nXhtml in Emacs. The error is

  Variable binding depth exceeds max-specpdl-size

This happens during fontification with MuMaMo. I have not been able to
reproduce this problem myself, but another user, ecce, has seen the
same problem. It disappeared however when he upgraded. (I have asked
ecce to test the file Chris have problems with too.)

I do not have any idea about what is going on. Chris has tried to
raise max-specpdl-size to 100 000 but that did not help.

Could depends on whether (and which) files have been byte-compiled.

Thanks, Stefan.

Chris is using ubuntu and he said that he is using
"emacs-snapshot=1:20081205-1 installed from the PPA". I have just
asked him to check out and compile Emacs himself if he can.

I got this reply from Chris

  I built Emacs from source and the max-specpdl-error went away. On
  startup, emacs gives the warning

     Warning (initialization): Building Emacs overflowed pure space.
  (See the node Pure Storage in the Lisp manual for details.)

Is there perhaps a problem with the PPA distro in Ubuntu? Is this the
same as on Debian?

Seems like pure space shoudl be increased.

Romain, do you have anything to say about this?

Not really, no.  AIUI the pure space overflow applies to the OP's
self-compiled Emacs, not to the Ubuntu version (the Ubuntu build
scripts explicitly fail the build on purpose when that happens).
And there's not enough information about the original mumamo issue
to conclude that the problem is on the Emacs side.

What more information do you think is needed?

Another user now wrote on the bug page
(https://bugs.launchpad.net/nxhtml/+bug/300946) that he got the same
problem, but it went away when he compiled Emacs himself. (He did not
mention the pure space problem.)

Is it possible that you can upload a new snap-shot so we can see if
the problem is gone there?

That could mean that the error is triggered by a system
configuration file (under /etc/emacs/site-start.d); contrary
to the packaged version a self-compiled Emacs doesn't load them.

The error happens when emacs is started with "emacs -Q". Do you mean
that the conf file above is run then?

No, it's not.
