No, I'd say either the 'tcp' or 'tcp_oos' suite is broken.

Well, they seem to work for most people..

Did you try running just the tcp test? What happened?

At least no crashes ...

If your problem with the pbuf test is that it calls LWIP_ERROR(), define that macro so that it just runs the last argument (return errorcode)

instead of asserting or whatever.

For sure, but where? I supposed the unit-test should detect this.
Some problem with Check or my lwip-config...

Do you run with your own lwipopts? The tests are meant to run with lwip/test/unit/lwipopts.h

I guess that is why you get igmp included, that is not enabled by default.
