Hi All,
 
I wrote a binding to matlab matrix.h and mat.h.  My test program works when I compile a binary, but when I try to use the code in ghci nothing happens.  There are no error messages, but all computations return a blank line.
 
Does this fall into a known class of error?
 
I can provide my source code, but because of licensing requirements I can't provide the .dll's against which the code is linked.
 
TIA
