Description aragorn 2003-04-19 09:44:48 UTC

Version:           3.0.0a4 (using KDE 3.1.9)
Compiler:          gcc version 3.2.1 20021207 (Red Hat Linux 8.0 3.2.1-2)
OS:          Linux (i686) release 2.4.20

Hi....

	KDevelop locks without chance of getting it back when the cpp parser tries to parse a file with macros, i was trying to write something like the following:

#define TRY_TO_LOAD_PLUGIN(csref, obj_ref

and just there it locked, and had to do a kill PID.

	Kdevelop has evolved a lot, i hope it continues to improve :)

	thanks for reading...

	Cheers...

	PS Also as a wishlist: it would be nice to be able to set foreground white and background black for the qeditor part, actually you cant change the background color, both for highlight and when editting plain files :)...Thanks....

Gideon 3.0.0a4 (KDE 3.1-10)
gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
Linux version 2.4.20-9

I'm also seeing this with alpha4 and cvs.
Here a backtrace of active threads when the lockup happens:

It also locked when I tried to #include a .h file that was created by  the New Class 
wizard.  
 
I typed  
 
#include "vrmainwindow. 
 
and after that it locked.
