After compiling and downloading to FPGA, I'd run NIOS II and got this error. How can I fix this error?

Which version of Quartus are you using? IIRC this is a common problem with Cygwin. If you search the forum with cygwin, fork and/or "couldn't allocate head" you should have some answers.

Yes I think it was a very common problem with Quatrus II 9.0. I don't remember if there was a fix though.
