Re: Crash bug in 0.9.8n
Hi, The crash occurs with 0.9.8 because it wrongly calls the function close instead of closesocket in order to release the client socket. In the 1.0.0 source, this has been corrected but the modification has not been back-ported to the 0.9.8 source tree. Also, the crash occurs only if you compile with a recent VC++ runtime (like VC2008 and VC2005). With VC6 no crash happens. This is because recent VC++ runtimes call a default handler when a CRT function receives an invalid parameter and this handler simply aborts the program execution. This behavior can be changed by setting a custom handler using the function _set_invalid_parameter_handler. Cheers, -- Mounir IDRASSI IDRIX http://www.idrix.fr Thomas J.

No crash. Just like 1.0.0 (apart from the mysterious shutdown(2) called
on an what appears to be an uninitialized file-descriptor, which is
different between the two versions, 42 vs. 127).
