Honored ContributorThis isn't the 'usual' error (whcih is fork() failed), but it may be related to the large series of hoops that cygwin has to leap through in order to simulate fork() under windows (basically, it has to reload all the shared libraries at the same addresses (as in the parent) and hope that the relevant addresses are available foreach library) anti-virus software tends to make life more difficult than usual.
Someone said to me that cygwin has now implemented posix_spawn(), if the shell (and anything else that does fork-exec (like make)) use that instead then cygwin will have far fewer problems (and will be faster). I don't know whether any of the programs have been changed yet, and, in any case, I think Altera use their own copy of cygwin.
