Re: cygwin 1.3.10 mmap+fork+sockets=fixup_mmaps_after_fork

[Michael Potter <pottmi at lidp dot com>]

We downloaded the latest snapshot (6/4) and it still fails on win2k.
We are running the win2k box as a terminal server.

It runs successfully on ME with the 6/4 snapshot and with the 1.3.10.

Would anyone be interested in the strace of the failure?

Corinna, what opsys are you using?
