I can't reproduce this in the current cvs started with -Q.

Please set the following:

(setq bibtex-entry-format
      (append '(opts-or-alts required-fields numerical-fields)
              '(whitespace realign delimiters unify-case)))

I can reproduce this with GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of
2008-12-14 on BREPNB.

In future, please provide all the relevant information in the initial report.

This usually a complete, concise recipe starting from emacs -Q:


emacs -Q --eval "(setq bibtex-entry-format '(delimiters))" file.bib

where file.bib contains:

@misc{foo,
  month=sep # "~21",
}

I've installed a patch that should handle properly concatenated
fields like the above month field. Does it work for you?

Thanks,

Roland

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In BibTeX-mode run C-c C-c on this entry to get the backtrace.

@misc{dingle1976qeh,
  title={{Quantum effects in heterostructure lasers}},
  author={Dingle, R. and Henry, C.H.},
  year={1976},
  month=sep # "~21",
  publisher={Google Patents},
  note={US Patent 3,982,207}
}

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'.
If you would like to further debug the crash, please read the file
d:/Applications/emacs/etc/DEBUG for instructions.
