I can't reproduce this, it works for me all the time. > Attached is the output (p1.txt) from "strace cygcheck -p > strings.exe".

It doesn't return lots of usueful info under strace becasue this requires a Cygwin DLL, and cygcheck only loads the cygwin DLL at runtime, but doesn't need any of Cygwin's functionality for -p. The cygwin-debuginfo package adds symbols, this may be a big help debugging this problem.
