Subject: KDevelop reproducibly crashes when debugging empty program
From: inkclerks at rinkworks.com
X-KDE-Received: -24.48.222.148

Package:           kdevelop
Version:           2.1 (using KDE 3.0.1 )
Severity:          crash
Installed from:    Compiled From Sources
Compiler:          egcs 2.96
OS:                Linux
OS/Compiler notes: Not Specified

This error is in KDevelop 2.1, the same problem existed in an earlier version of KDevelop.

To produce this error, create a C terminal KDevelop project. Add a c file with these contents (note, it has to be a separate file):

void nuke()
{
}

then modify the main.c to look like this:

void nuke();
int main()
{
	nuke();
	return 0;
}

Build the project. Put a breakpoint on the call to nuke() and debug the program. Step into the function nuke() and then close the window with the function nuke(). Step again and KDevelop will crash.

The backtrace is as follows:
