Hi all,

in Kalzium we're reading chemical data from a global object named "etab" 
defined in an external C++ library, OpenBabel. It is defined in the source 
code of OpenBabel as
 	OBElementTable etab;

Since a few weeks, the data read from this object is corrupted. Most of 
the data that we read is just uninitialized values. Some data however 
remains valid.

Nothing has changed in Kalzium and in OpenBabel in this respect. Other 
(non-KDE) programs using OpenBabel do run fine, including a simple test 
program that I wrote for this occasion.

At least 3 Kalzium developers are experiencing this issue: Carsten 
Niehaus, Johannes Simon and myself.

So my guess is that something has changed in the KDE buildsystem, 
affecting the linkage to global objects defined in external binary C++ 
libraries.

Does anyone have a clue what that might be?

Thanks,
Benoit
