Has there been any change in this area since 7.0.50 12/02/09 snapshot?
I am using these options:
set target-async on
set non-stop on
set detach-on-fork off
and have a simple app that forks two processes. 7.0.1 fails to break on
already established breakpoints.
Any idea what might went wrong?

Here are the logs from 7.0.50 and 7.0.1 runs:
