Bug#2288: Including h-File into project

Subject : Including h-File into project

Error Class	: software bug
Error Location	: project management
Priority	: medium
Bug Description ---------------------------

The following header file ALWAYS causes kdevelop to hang when
scanning the project file. If it is included into the project the following
happens:
The file is displayed, the project is being scanned and at a certain
percent rate (dependent on the position of the file in the project) the 
progress bar stops and kdevelop hangs. kdevelop does not react to 
the x-Button on the window to close but closes on a SIGTERM then.
It uses full CPU when hanging but does not allocate any additional 
memory.

I am not sure, but I used the same h-File in kdevelop 1.0beta3 
without problems, but I still used my own Makefiles. Now it is a C++-
terminal application.

How to repeat the error -------------------

Create a new C Terminal application and include this h-File into the 
project. (h-File is called Math.h)

Bugfix or Workaround ----------------------

No.
