Subject: 24.2.50; invalid function when starting erc
Date: Thu, 18 Oct 2012 10:40:05 +0200

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

1) emacs -Q
2) M-x erc
3) Press enter repeatedly

Seems to be commit 110553 that breaks it.

Indeed, 110553 uncovered this problem.  Should be fixed now, thank you.

That's not enough, you have the same problem with
erc-with-all-buffers-of-server.  Basically what the autoload of erc-log
used to achieve was to load erc early enough so that the remaining macro
uses are known to the byte compiler (and that autoload is useless now
that erc-log isn't a macro any more).  Unfortunately there is a circular
dependency between erc and erc-backend, so we cannot just require erc
early.  When I try (eval-when-compile (provide 'erc-backend) (require
'erc)) I get a lot of "might not be defined at runtime" warnings, but
all macros are expanded (including the erc-log defsubst).  Not sure
what's the lesser poison.

Andreas.

I think I found an acceptable solution (taking your lesser poison and
removing the eval-when-compile).  It also fixes the "Eager
macro-expansion" warning.  Thanks,

Yup it's fixed, thank you!
