I reproduced it again.  The error messages are as follows:

./myscript.sh: line 32: /usr/bin/cut: Cannot allocate memory
./myscript.sh: line 32: /usr/bin/md5sum: Cannot allocate memory
./myscript.sh: line 32: /usr/bin/grep: Cannot allocate memory
      1 [main] sh 437152 fork: child -1 - CreateProcessW failed for
                         'C:\cygwin\bin\sh.exe', errno 12
./myscript.sh: fork: Cannot allocate memory

...and the script aborts at that point.

So, this totally confirms everyone's responses that the issue is related to 
forking.

Thanks all...
