Comparing with guitest.C and especially its TestMsgBox, they are
strikingly similar. They both call their overwritten CloseWindow() member
function that is simply "delete this;". However, one class works
flawlessly and the other one doesn't.
You can have a look yourself in
<your_brop_dir>/monitor/abc/BrPrintManager.cxx:
PrintDialogBox::SetupWindow

Yes, apparently I did "gdb supermon" on the binary generated with
"make" (not "make install") and got the error message:
"/home/bergen/jens/brahms/brop/monitor/apps/supermon": not in executable
format: File format not recognized.
However, when I run gdb with the binary created with "make install" it
works fine.
So, the output from gdb indcates that it is the resizing of the printer
dialog that causes trouble:
% gdb supermon
....supermon initialization output.....

Here a print dialog is opened successfully for the first histogram to be
printed, giving the first "Trying to print....." line at stdout. When the
second histogram is to be printed the seg.violation occurs.

That's the bash way of doing it. How about csh and its decendants? Maybe
your proposed arguments to configure (below) should be included right
away.

I suppose we could do that.
