[Doxygen-users] Segfault

[Berno L. <ber...@ep...>]

Hello!
 
I have a project that uses Qt. Therefore I create a Doxygen-Documentation of 
the Qt-Classes and let Doxygen produce a "tagfile.qt".
 
If I create the docu of my project and use the "tagfile.qt", I get a segfault.
 
If I do the same, but don't use the "tagfile.qt", all runs as expected.
 
Ok, I admit that the Qt-Library isn't the "small example" that Dimitri always 
requests to find the error :-)
 
The last words of Doxygen before the segfault are:

As workaround I put an if clause around the cl=fd->getUsedClasses() in 
function findClassDefinition in doxygen.cpp:
 
if ( fd ) {
    cl = fd->getUsedClasses();
}
 
After that it works for me, and the resulting Documentation seems to be ok.
 
Any hint where I should look in the docu what could be missing?

PS: I use Doxygen 1.2.8-20010617 and the qt-copy of KDE

PPS: How can I activate the debugging output of Doxygen? I converted all 
Debug::print commands that interested me to printf to find the error ...
