You told us nothing about what versions of Windows, Cygwin, and PHP you are running, so WAG, either: - you have defaulted to or specified a PHP configuration limit of 4MB memory for PHP tasks, or - if you're running 32 bit Cygwin, possibly under 32 bit Windows, you have probably run out of heap space from installing too many packages requiring too many DLLs. If you are running something else, you need to tell us about those, following the problem reporting guidelines linked below, including copying verbatim all error messages seen, and PHP build configurations and logs. -- Take care.
