I'm confused.  Do you mean the code compiled on the sane machine, where
the binary runs ok when compiled with the older binutils, is crashing
when simply copying the executable to another machine?  Isn't it a
cygwin problem then and not an issue which version of gcc or binutils
is used?

I get the same result when running a binary compiled with gcc-3.4.4 /
binutils-20050608-2 / cygwin-1.5.17, here it is running fine, running
the idebntical executable at another box with cygwin-1.5.18 gives me
the crash.

When compiled on this machine, what is the cygwin version and what is
the cygwin version on the box where it works ok?
