+** 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 version 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
