Thanks Marco,

pthread_mutex_init calls calloc under cygwin but does not allocate memory under 
linux, so not invoking pthread_mutex_destroy causes a memory leak only under 
cygwin.

thanks for the work .

uploading 1.8.3-2 on www.cygwin.com

Thanks Marco,

pthread_mutex_init calls calloc under cygwin but does not allocate memory under 
linux, so not invoking pthread_mutex_destroy causes a memory leak only under 
cygwin.

Thanks Marco,

I could reproduce the issue even with one node sending/receiving to itself.

I will investigate this tomorrow
