I think that should be removed. Thomas

I think that should be > removed. Well, I thought of that, but then I followed the example in soreadbuf() in this same module where these relatively rare, maybe never, conditions happen. If a bug report came with some stderr output maybe a useful solution could be provided. In both cases, these are error path situations which the code should handle cleanly (without leaking memory or sockets). I did not actually encounter this issue during execution. I merely noticed the problem during a code review while porting to windows. I'm not stuck on this, but having these there (in both cases) seems at least consistent with the other code in the same module. A different effort could be pursued to enable these and other cases where stderr is written to in the slirp code and only produce it in debug mode. This patch is trying to minimize changes now. Other commits supplied with this one generalized the existing explicit debug output calls produced by the DEBUG_CALL, DEBUG_ARG, DEBUG_ARGS, DEBUG_MISC, DEBUG_ERROR and DPRINTF macros. If more comments come back on the rest of those patches, I'll either add an additional patch set to the existing ones to remove the explicit references to stderr and use the various debug macros as needed or I redo the whole patch set. Please suggest the best course of action. - Mark
