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':

The recipe is:

  configure
  make bootstrap

Since about 2 weeks ago, I see these warning messages while
bootstrapping on MS-Windows, when Lisp files are being byte-compiled.
Two typical examples:

  Warning: Eager macro-expansion skipped due to cycle:
    Γאª => (load "erc-backend.el") => (macroexpand-all (defun erc-server-connect Γאª)) => (macroexpand (erc-log Γאª)) => (load "erc.el") => (load "erc-backend.el")
  Wrote d:/gnu/bzr/emacs/test2/lisp/erc/erc-autoaway.elc

  Warning: Eager macro-expansion skipped due to cycle:
    Γאª => (load "tramp.el") => (macroexpand-all (defun tramp-action-login Γאª)) => (macroexpand (with-connection-property Γאª)) => (load "tramp-cache.el") => (load "tramp.el")
  Wrote d:/gnu/bzr/emacs/test2/lisp/eshell/esh-module.elc

(I don't know what is that binary garbage, maybe some byte code.)

AFAICS, all of these messages are related either to loading tramp.el
or erc-backend.el.  But I may have missed others, not sure.

Please remember that byte compilation during bootstrap on Windows is
done with an Emacs binary dumped with .el version of the byte compiler
and its subroutines.  I never saw anything similar in "regular" byte
compilation after updating from the master repository, FWIW.

If I can give more information about this, please ask.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
d:/gnu/bzr/emacs/trunk/etc/DEBUG.
