gdb and threads
Fri Jun 23 06:48:00 GMT 2000
thanks for the info chris ...
another problem I'm having with gdb is that the "variable balloons" only
show up about half the time. I can see why it might have problems with c++
classes, but sometimes variables of type 'int' won't even come up (either
intialized or uninitialized)
(I am using gdb 5.0)
