15 years agoI think this is purely a cygwin issue. I've seen it with cygwin on Vista, and a web search found a cygwin thread implying that a bug was found that caused this under some circumstances, and it's been fixed. I updated my cygwin install on Vista and that fixed it.
So, for Quartus/Nios purposes, this will probably get fixed in a future release if Altera uses an updated version of cygwin. The thread I found didn't suggest what conditions might cause this or what workarounds might help. I don't know if you can use a separate cygwin install and run the Altera tools from it. \c
