[DGD] my dgd is VERY crashable

[Robert Forshaw]

I'm using DGD 1.2p3 for windows with // patch (although I tested it without 
the patch and the problem persisted).

First of all, if there is a compile error when attempting to start the MUD, 
any subsequent attempt to restart the MUD, even if the compile error has 
been rectified, will result in a crash and a Windows XP 'There has been a 
problem' window.

Also if there is a runtime error, the mud will crash the next time something 
happens (I haven't really explored what 'something happens' means exactly, 
this since I don't make a lot of runtime errors, but it usually crashes when 
I enter any further input to the mud).

The main prob right now though is that when calling a prototyped function, 
the driver will quit without fail (no actual crash as far as windows is 
concerned, the DGD window just vanishes and the driver shuts down).

I've uploaded driver.c and user.c to my site. I have tried running Kernel 
and it doesn't seem to have any of these problems, so it is probably 
something wrong with my code (although I think DGD should be more resilient 
to errornous mudlib code, shutting down entirely doesn't seem very 
healthy...).

In user.c, the second problem I described (where it shuts down) occurs when 
the species_selection_menu() function (line 118) is called from 
process_character_creation_input() (line 104). The MUD exits. However, the 
MUD doesn't exit if I comment out line 127 (where character_creation() is 
called). However the MUD just hangs around in limbo then which is not what I 
want. I have also tried repositioning these functions so that 
character_creation() is the prototyped function (rather than 
species_selection()) and species_selection() definition is positioned before 
the character_creation() definition. The same thing happens, and is 
preventable by removing/commenting the character_creation() line in the 
species_selection() function.

It also appears that the error doesn't occur during runtime, since I insert 
messages between the code and I don't see those messages even though they 
are displayed before the call to character_creation() occurs (which is what 
appears to be causing the exiting since commenting it out stops that from 
happening).
