emacs-22.1 with GTK dumps core when Gnome wigets clicked

[Gary Mills]

Clicking on any of the `Specify a new file name', `Read an existing file',
or `Read a directory' icons causes a core dump.  This happens on both
Solaris 10 SPARC and Solaris 10 x86 compilations.

Here's part of an analysis on the core:
$ mdb $(whence emacs) core

I was able to prevent the core dump by adding:

  #define SYSTEM_MALLOC

to src/s/sol2-6.h and rebuilding and reinstalling.
