lwIP sequential Assert cyg_Mbox

Felix R
Hi,

the sequential http-test fails with an assert.

ASSERT FAIL: <5>mboxt.inl[79]void Cyg_Mboxt<T, QUEUE_SIZE>::wakeup_waiter() Bad thread pointer
or:
ASSERT FAIL: <5>mboxt.inl[605]cyg_bool Cyg_Mboxt<T, QUEUE_SIZE>::tryput() Bad this pointer

I cannot figure out the reason. can you help me?
