TCPServer::accept() hardfaults if maximum number of sockets open

[tommikas]

1. Open 4 sockets, at least one of which is a TCPServer type socket
2. bind the server socket and set it to listen
3. call accept() on the TCPServer socket

Can you provide a code snippet? This will help increase the time it takes reproduce and fix.

I would hope it'd have the opposite effect ;)

Anyway, I hacked mbed-os-example-blinky a bit: https://gist.github.com/tommikas/870cc1a7f50bbf0643d7bc47e6cf5392
(The same result could be achieved by the example in the issue that referenced this one.)

Thanks for reporting this, that is an interesting corner case but should be easy to fail gracefully (returning NSAPI_ERROR_NO_SOCKETS)

[tommikas]

That sounds like a more reasonable way to handle it.

#2579 should resolve this problem as suggested. Let us know if there is still an issue.

This has been fixed. Closing.
