Sounds like a problem that has been solved previously.  Try the following:

Open regedit (or regedt32) and find the key
HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin\

Create a new DWORD value there called "heap_chunk_in_mb" that contains the
maximum amount of memory (in Mb) your application needs (watch the
hex/decimal toggle). Exit and restart all cygwin applications.

The default is 128 (i.e. 128Mb) if no registry key is set.
