Title: Fatal Crash while removing tools
Post by: Biplab on May 21, 2007, 08:52:02 pm

A fatal crash can be observed while removing tools from Tools menu. To reproduce the crash do the following,

• Add a tool using Tools>Configure menu option and click OK. Now the added tool will be available under Tools menu.
• Delete the newly added tool using Tools>Configure menu option and click OK. Now C::B will crash.

The crash is not observed if:

• A separator is added & removed.
• If tool list is not empty.

The backtrace is as follows:

C::B crashes at line 92 of sdk/menuitemsmanager.cpp file where subMenu->GetMenuItemCount() has been called.

If anyone has a fix please post or apply it in SVN.
