bug#13924: 24.2; Recompile and compile-environment

From: lars
Subject: bug#13924: 24.2; Recompile and compile-environment
Date: Mon, 11 Mar 2013 10:13:34 +0100
User-agent: Gnus/5.11 (Gnus v5.11) Emacs/22.1 (gnu/linux)

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 acknowledgement 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':

This lisp code starts a compilation with the provided environment:

  (let ((compilation-environment '("FOO=BAR")))
    (compile "printenv"))

Typing 'g' or 'M-x recompile' in the *compilation* buffer starts
another compilation with the same environment.  This is evident since
the printenv output includes FOO=BAR.

However, typing 'M-x recompile' in some other buffer will not use the same
environment as the first compilation.  FOO=BAR is no longer present.

This behaviour may be a bug or a feature.  However, in my opinion it
renders the combination of 'compilation-environment' and 'recompile'
somewhat useless.

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'.
