Wireshark-dev: Re: [Wireshark-dev] Compiling under MSVC 6.0 - simple Q, clear cut A ?

I read through this thread with keen interest as I am experiencing similar
issues.

I am a UNIX developer (literally) but am currently developing Wireshark on
Windows so there could be operator error involved.  I've been successfully
building using MSVC and nmake for the past couple years and only recently
decided to use MSDEV for debugging.  I get the usual initial pause in
..\gtk\main.c but pressing F5 to continue causes the unrecoverable error -
"Unhandled exception in wireshark.exe (LIBGLIB-2.0.0.DLL) Access violation".

If I run wireshark.exe outside of the debugger it performs perfectly.  Has
anyone seen this before and know the root cause?

I've carefully followed the advice on the wiki and have pointed MSDEV to the
source code and .bsc file.  I've tried both attaching MSDEV to a running
instance of wireshark and also allowing MSDEV to spawn the instance.  Both
experience the same failure.

Cheers
Bryan

An alternative way to do this is to:
1. Start wireshark.exe and msdev separately.
2. In MSDEV 6, choose menu "Build" -> "Start Debug" -> "Attach to process" 3.
>From the list of processes, choose wireshark.exe (most certainly one 
of the topmost items).
4. Load the source file in which you would want to set a breakpoint 
using the menu "File" -> "Open".
5. Set a breakpoint at the desired line in the source code.
6. Wireshark will pause its execution once the breakpoint gets hit.

Note that if you upon closing MSDEV answer yes to the question whether 
the debug session's opt file should be saved or not, then you can open 
MSDEV the next time and just reload the debug workspace from the menu 
"File" -> "Recent workspaces". Once the workspace has been loaded, you 
can start the Wireshark execution (in the debugger from the beginning) 
using for instance "F5", "F10", or "F11".
