Please provide a 100% reproduceable test case, either an existing OSS application included in Fedora Core, or a standalone test case exhibiting the problem. Thanks in advance. Setting status to "NEEDINFO"
Ok, here is more info - I think I have narrowed this down enough. As I mentioned before XtVaOpenApplication is crashing on me. The exact application works fine under FC3. After updating to FC4 it no longer works. The small app below demonstrates the problem. I can reproduce by changing the compile line and re-running. BTW, The program crashes when run - not during the compile. Under an updated (6/24) FC4 system with xorg-x11-6.8.2-37 Result RUNS: g++ test.C -o test -lGL -L/usr/X11R6/lib -lXt Result RUNS: g++ test.C -o test -lGL -L/usr/X11R6/lib -lXm Result RUNS: g++ test.C -o test -lGLw -lGL -L/usr/X11R6/lib -lXt Result DIES: g++ test.C -o test -lGLw -lGL -L/usr/X11R6/lib -lXm My conclusion is that there is some weird interaction between libGLw and libXm most likely in their library startup/init code. As you can see only the first compile/link line is needed for this little app but my app uses GLw and Xm so that is the one I use for my real app. On an FC3 system with xorg-x11-6.8.2-1.FC3.13 all four versions work. Sample Application: #include <iostream> using namespace std; #include <Xm/Xm.h> static String fallbackResources[] = { NULL }; int main( int argc, char ** argv ) { XtAppContext _theApp; Widget _baseWidget; cerr << "1" << endl; _baseWidget = XtVaOpenApplication(&_theApp,"Test",NULL,0,&argc,argv, fallbackResources, applicationShellWidgetClass, NULL); cerr << "2" << endl; }

This may have the same root cause as bug 163017. The symptoms sounds similar.
Yes it does seem like the same problem. Kinda quiet here....
