  Well, there's two possibilities:

1)  You have a stray pointer or malloc bug (or one of various similar
problems) in your code, and it just happened to work and not crash by luck
on Unix; minor differences in process layout and environment cause the
underlying bug to be hidden in Unix and exposed in Cygwin.

2)  You've found a bug or unimplemented feature in the cygwin api.

  If you're mentioning structs, my guess is you're doing something wrong
with pointers or arrays.  It's a very common thing in C.

Can't think of a witty .sigline today....
