More memory stuff with some interesting output

[David Allen <opop erols com>]

Ok, I claimed that glib was lying to me, I also claimed that I was having 
memory problems that I couldn't sort out.  Here is a snippet of code, 
and the output of g_mem_profile, maybe this will point out what the problem
is, (possibly something wrong with gtk+?  Usually that's the last thing I 
would assume as I have been known to make mistakes just like everybody else)

Vital statistics about me (All the results of rpm -q's):
gtk+-1.2.3-1
glib-1.2.3-1
egcs-1.1.2-12
glibc-2.1.1-6
XFree86-libs-3.3.3.1-52

The code snippet....

<CODE>
fprintf(Q,"Before gtk_init...\n");
g_mem_profile();

gtk_init(&argc, &argv);

g_mem_profile();

gtk_main_quit();
g_mem_profile();

gtk_exit(0);
</CODE>

The program does a few miscellaneous things before hand, (which are reflected
in the g_mem_profile right before gtk_init() and there is one outstanding 
variable which at that point SHOULD be outstanding)

I just added the gtk_main_quit right after gtk_init to prove this point - as
you can see, no widgets were made/destroyed in the code.

And the output:

Gtk-CRITICAL **: file gtkmain.c: line 534 (gtk_main_quit): assertion `main_loops != NULL' failed.
(Comment - I'm guessing this happened because I cheated gtk out of getting
to deal with any signals and so on - normally it doesn't happen when I do
things between gtk_init and gtk_main_quit)

(Comment:  gtk_exit(0) gets called)
</OUTPUT>


ca 42k of unfreed memory???  When I run the whole application without just
making it take a dive right after it starts up like I did above, it ends up
with 300k unfreed memory.  Some of that may be me, but I've checked through
many times, and I'm thinking most of it is gtk+
