Also, look through your old glibc email archives. I emailed you about this in March of 1998. 1998-03-29 SL Baur <steve(a)altair.xemacs.org&gt; * emacs.c (voodoo_free_hook): ELF libraries built with newer versions of GCC do horrible things in dumped binaries after exit() is called. (Fkill_emacs): Use it. The patch looks O.K. and Wolfram's analysis is correct. I no longer have access to the machine where XEmacs crashed 100% of the time at exit due to a double free, but hopefully I can duplicate it on a different machine and verify that this fixes the problem without voodoo_free_hook and turning off free at exit(3) time. -- I protest the NATO war in Yugoslavia.
