Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list, and to the gnu.emacs.bug news group. Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I ran into the following situation yesterday: I ran one compile command in the morning. Then, for the rest of the day, I ran a couple of different compile command, alternating them many times. Near the end of the day, I wanted to re-run the first command, but it had been removed from history. It would be nice if there were a way to eliminate duplicates from compile-history, so that older commands were not completely dropped. For instance, a command could still be put at the front of the list; but all duplicates of it elsewhere in the list could be removed at the same time. 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 /usr/share/emacs/22.2/etc/DEBUG for instructions.

C-h v history-delete-duplicate RET history-delete-duplicates is a variable defined in `C source code'. Its value is t Documentation: *Non-nil means to delete duplicates in history. If set to t when adding a new history element, all previous identical elements are deleted from the history list. (inspired by tcsh's histdup) This works on all histories, not only compile-history.
