Crash on Zone

Tried setting up the debugger like Lax said... never could get a dissasembly window, and never got green arrows pointing at source code lines... and yes, mq2 was compiled on this computer...
Did get the following lines in debug:
First-chance exception at 0x01aa2e9c (MQ2Map.dll) in eqgame.exe: 0xC0000005: Access violation reading location 0x2a510aec.
First-chance exception at 0x004c5317 in eqgame.exe: 0xC0000005: Access violation reading location 0x00000000.
Hope that helps.

I also saw some CTD issues while zoning.
Only happend when using MQ2chat as opposed to MQ2chatwnd
If i get a chance tommorow, I'll try and debug to provide more info.

Same thing happened with me, I loaded mq2map and debugged and came up with the same output as the orginal poster. Unloaded mq2map and it worked fine, only crashed with MQ2 loaded before starting EQ and while zoning.

Code: Select all
First-chance exception at 0x01aa2e9c (MQ2Map.dll) in eqgame.exe: 0xC0000005: Access violation reading location 0x2a510aec.
First-chance exception at 0x004c5317 in eqgame.exe: 0xC0000005: Access violation reading location 0x00000000.
This isn't what you wanted? That is what turned up in output window when I debugged using VC6. I may be new to this, but I am trying my best to learn everything I can about it.

What's the very first topic in this (MQ2::Bug Reports) forum?

Hey don't yell at me I was just quoting the guy 8)
Also, the insturctions are for Visual Studio.NET which I am not using, so I did the best I could using a different program.

You have visual studio 6, which VS.NET is based on.. You managed to attach the debugger, it's not very difficult to find the stack frame, etc. What are you stuck on?
We still need each piece of info from the list in order to help you.

I am also using Visual Studio 6.
Ran the debugger.
Found a similar string to the one above, only it concerned MQ2Main.dll, however not the point of this post.
Now, I ran the Dissasembler (Alt+8), it automatically closes upon crash, not revealing any information.
I open "Call Stack", window opens containing the text:
Code: Select all
(call stack unavailable while child is running)
I am no pro using this program, if anyone would like to provide assistance on how I can further attain information on what is causing the crash through the debugger, I would be happy to post my findings. I just am not sure what to do to make the debugger work for me, heh.

(call stack unavailable while child is running)
That would imply EQ didnt crash, it was still going.
To make it stop on every "Access Violation" instead of possibly continuing...
(VC6): After you've attached to the eqgame.exe process go Debug->Exceptions. The 4th one down should be "C0000005 Access Violation" and it probably says "Stop if not handled". Select it, and then in the "Action" box right above the list click "Stop Always" and then hit the "Change" button. Hit OK.

Sorry, that doesnt help.
We need the source line and call stack (at LEAST the call stack) if it's in MQ2, which it is... I cant do much with that ;(
Go down the list of items in the "how to report crash bugs" and get as many of them as possible for me please... instead of the disassembly (which is only useful inside EQ) and the address (which is only useful inside EQ)

This might be a little more along the lines of what Lax is looking for. Well that and I am hitting this bug also with latest :)
What I did to get this for people who are not using VS was to.
1. ntsd -oGgpn eqgame.exe
2. ctrl+c
3. .sympath c:\program files\macroquest2 (note this just happens to be where I put my MQ and symbols at)
EDIT: 3 and a half. oh yeah forgot to put type g and hit enter so the program starts again :)
4. when it crashes type .lines
5. and then kb
Code: Select all
