Hello,
gcc 3.1 is by now rather old. Is it possible for you to determine
whether this problem still exists on gcc 3.3 branch or current
mainline? Thanks,
Dara

Thanks for the update. Sorry that there hasn't been
any progress...

Any platform that supports GNAT.Sockets.
>Description:
Create_Selector creates a signalling socket in an unsafe way. A malicious local user (or, if the host implements a sufficiently weak end system model, someone on the local network) can connect to the newly created socket before the application itself, thereby disrupting normal operation.
>How-To-Repeat:
>Fix:
Switch back to using pipes instead sockets for signalling, as in GNAT 3.14p.
On platforms which do not have pipes, use UDP for signalling, and add some kind of check that the triggering
UDP packet really originated from the program itself.
