Message-ID: <200605282354.k4SNsLC1003677@jane.dms.auburn.edu> (raw)
If there is pure space overflow, the warning messages refer to the
node Pure Storage in the Elisp manual. But that node nowhere mentions
the problems that pure space overflow causes (a very bad memory leak).
I propose the following minor changes to internals.texi. I can
install if desired.

the part that didn't fit. If that happens, you should increase the
compilation parameter @code{PURESIZE} in the file
@file{src/puresize.h} and rebuild Emacs, even though the resulting
! image will work. Such an overflow normally won't happen unless you
try to preload additional libraries or add features to the standard
ones. Emacs will display a warning about the overflow when it
starts.
