DDD with Mesa

[D.J.Allerton]

Hi

I'm using Mesa (Open-GL) with Red Hat 8 for real-time double buffered 
applications.
My software is written in Gardens Point Modula-2. I installed DDD and it 
works fine
for debugging Modula-2.

However, when I try to debug Mesa code, I can set breakpoints etc but 
the breakpoints
never get activated and DDD hangs. I know the code reaches this point as 
I can print out
diagnostics. DDD does not respond to killing by control-C and I have to 
reboot Linux
when this occurs.  The software does not hang at all if I run it without 
DDD. The Mesa
double-buffered code is part of GLUT, which enables the user to define a 
display process
and an idle process.

Many thanks

Dave Allerton
