Well, this shows that you can run "id" with no crashes...

The included strace lines look like a normal termination sequence...
However, the strace output you've attached says

   Program name: c:\cygwin\bin\id.exe (2476)

at the top, which means you ran "id", not "cygcheck -s" under strace.
The idea was to try to get "cygcheck -s" to crash under strace, and see
what the last action before the crash would be.  Could you also run
"cygcheck -s" under gdb and see if it crashes?  If it does, try to get a
backtrace.
