[3.03a] Crash creating new map in offline session
|
While attempting to create a test case for another bug, I managed to find this one. I have crashed CMUD 3.03a three times in a row while trying to create a new map in a (new) offline session:
PROCEDURE
- Start CMUD 3.03a
- Create a new session 'sess1'. Don't fill in any hostname, port, etc. info (I had only intended to use this offline for testing).
- Open sess1 offline.
- Click the Map button in the toolbar to bring up the map window
When I do this, the Map window appears (docked to the right of the sess1 window, and it starts in to create a new map for this session. Partway through, it crashes as follows:

error details:
1) Start CMUD 3.03a
2) Create new session "sess1"
3) Open sess1 offline
4) Click Map button to open mapper
.
Program crashes as shown, with the message 'Creating database...' in the status bar of the mapper window.
|
Crash dump also submitted through the program, along with screenshot.
If I start up the program again, and simply open sess1 offline, I can open the mapper, but I can't create any rooms in it. If I delete the session, and delete the folder for the session, then reproduce the steps above, it will crash again. |

I am having a heck of a time trying to reproduce this one. The instructions seem straight-forward, but it doesn't cause any problem on any of my systems here. Can anyone else reproduce this?

*grumble*
And now it's not happening on mine anymore either. Happened three times in a row, now gone. A pox on all intermittent bugs.
FWIW, I have not rebooted since the bug was first discovered, but I have restarted CMUD 3.03a several times, fiddled with the mapper in working sessions, etc.
I guess this goes in the WTF file until I can find something more reproduceable. |

Given that the crash was in the "ShowHint" routine in CMUD, it's possible this bug depends upon exactly where the mouse cursor is when you create the new map. I put it on my bug list to look at the ShowHint routine to see how it might crash in weird cases.
