[Fixed for V0.40] RTC 39 crash

Post by **Lunever** » Tue Jun 13, 2006 2:01 am

RTC (V0.39) Diagnostic file - Mon Jun 12 16:31:47 2006

Error:
an access violation exception.

Stack Dump:

RTC.DrawDungeonView(char 30, char 32, char 1, char 2);
RTC.ProgStateInDungeon();
RTC.DoFrame(int 50);
RTC.WinMain();

It occured during normal gameplay. I've been throwing a knife and immediately after that pressed ESC to freeze the game in order to handle a real-world distraction. I could do so then, since the game crashed.

Hmm - well the point at which the crash occurs, the engine is drawing the dungeon view so nothing to do with pausing. I suspect that you pressing the pause button is a complete coincidence.

At first glance it looks like the DirectX surface has suddenly vanished and so all RTCs pointers to the surface are no longer valid. Is it possible you ALT+TAB-bed out of RTC or did something else involving swapping / moving / resizing of windows at the same time?

No, I didn't do anything else and I didn't change task by <Alt+TAB> or anything similar.

But right a minute ago I encountered another crash (btw on my other machine, the desktop, the earlier crash was on the laptop): I played, quit the game, restarted it after a couple of seconds, and the got first an error message window that said "RTC -Terminal error" and a text saying that the screenmode couldn't be set to the usual resolution and recommended to change it in the config file (Of course there's nothing wrong with the config, since the game always has been working with it). Then the diags was created as usual:

RTC.RTC_Init();
RTC.WinMain();

The screen-mode not able to be set usually happens because RTC hasn't fully closed on the last crash -- check your processes using Ctrl+Alt+Del and terminate any rogue instances.

Now that is definitely a problem with DirectX - RTC is just passing on a message it's received from the DirectX interface.

Of course, the question is, did RTC do something bad when you first played, which meant that the second time you played there was a problem.

Can you reproduce the problem?

Gambit: There wasn't a first crash on this machine - the other crash was on the other machine.

George: Nope, there wasn't anything unusual in RTC and I can't reproduce it.

Right, it happened again. I did change the resolution from x24 to x32 now as suggested by the first error message to see whether this will prevent that bug from reoccuring.

Did that help?

Fixed this for V0.40 (i.e. after DirectX barfs, RTC won't then fall over too!)

I don't know whether the config change helps, because I've not been at the desktop since. But I will let you know.
