Thanks.  I'm no longer sure that my assumption about WM_PAINT was
correct.  I don't have Babylon where I'm typing this, so how about if
you try to see what message(s) Babylon sends us?  For example, using
Winspector (http://www.windows-spy.com/).

I don't see that my backtrace is more detailed than yours.  Note that
in your case we are deep inside system DLLs, where debug info is not
available.  For our functions, you get all the arguments and the
current line, AFAICS.  Am I missing something?

Anyway, the only gotcha with DrMinGW I know of is that the program
must be built with -gstabs, as it seems not to support DWARF-2 right
now.
