Crash when changing the Build Target

[gmb300]

Reporting a Crash in Code::Blocks.

How to Reproduce:  :?
1). Open a project.
2). Close the project.
3). Manually edit the project .cbp outside of codeblocks (does this matter?).
4). Open a workspace containing the project.
5). Change the active build target using the combobox in the toolbar.
6). Crash...

I forgot to mention in the above report... By restarting Code::Blocks and everything works fine.  Sometimes, after making big changes to the project settings, and then changing the build target, the crash happens again.

3). Manually edit the project .cbp outside of codeblocks (does this matter?).

Sure. C::B itself is the only instance that is allowed to do such.
Everything else is like using a hex editor to write some stochasitic patterns in an executable and hope it's still running afterwards. ;-)
With regards, Morten.

My saying! 

But seriously, I don't think it is the reason for the crash. The project files are actually quite robust and should take a lot of abuse before something crahses.
Those 20 ProcessEvent calls don't look good... dread to think what it might be...

Bug fixed, thanks for providing a reproduction procedure. I 've been seeing this from time to time but could never reproduce it in a reliable way to debug it .
