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:
