Follow-up Comment #1, bug #44595 (project lwip):
The problem of not setting last_err actually got worse with my last cleanup of
fixing race conditions in that area. I've decided to prefer fixing race
conditions over setting last_err and discussing the arising problems
seperately (like here :)
The problematic calls are recv and accept, as these are done in the
application thread, not in the tcpip_thread.
The problem is that we have to watch out for race conditions when writing to
last_err, expecially when writing an err_t that is marked FATAL. (I have to
admit though that I never fully got the FATAL thing...)
