I think there is no harm documenting this, in case anyone happens to
use the affected versions of glibc.  I'v added the following text to

** Emacs crashes on startup after a glibc upgrade.

This is caused by a binary incompatible change to the malloc
implementation in glibc 2.5.90-22.  As a result, Emacs binaries built
using prior versions of glibc crash when run under 2.5.90-22.

This problem was first seen in pre-release versions of Fedora 7, and
may be fixed in the final Fedora 7 release.  To stop the crash from
happening, first try upgrading to the newest version of glibc; if this
does not work, rebuild Emacs with the same version of glibc that you
will run it under.  For details, see
