bug in apell when using pipes?

Incompatibility in aspell which causes the program belly-up.

The use of th "-a" option,"ispell -a" compatibility mode caused aspell to 
die with the unintuitive error message: 
   ==>  Error: nroff: dlopen returned "No such file or directory".

This appears to happen in the pipe() function.  I am not a oop programmer so its gets kind of hard to follow.  One of you familiar with c++ and the code .. please take a look at this.


$ aspell -a
   ==>  Error: nroff: dlopen returned "No such file or directory".

Does this happen systems other than cygwin?

All I used was gdb's n so I don't know how gdb jumped to L# 47 of stack_ptr.hpp

Help me track down this bug, so that the many people who are forced to use cygwin can benefit from using the aspell program as well as cygwin emacs users.
