Previously I had written:

Since then, I've turned off the Allegro keyboard handler to enable a full 
report of the errors.  First, when it freezes initially with just a black 
screen, i have to press CTRL+ALT+END to get the following error:

    Shutting down Allegro
    Exiting due to signal SIGINT
    INTR key Pressed at eip=000339d7

after which the program is still frozen.  Then, the only way to get a 
response is to then press CTRL+BREAK, which produces

    Exiting due to signal SIGINT
    Control-Break Pressed at eip=00033957
    eax=001248b8 ebx=00113800 ecx=00113800 edx=001248bc esi=00114838

      0x005a5a20

Then, if I do this from RHIDE, the following appears in the "Message Window":

    Call frame traceback:
    in function free+275
    in function _unload_datafile_object+55

I have very little of an idea what all this crap means.  I hope that this 
information can assist somebody (i'm no that somebody) :)
