That appears to be a bug in Windows' msvcrt.dll. cygcheck is not a Cygwin application, but a native Win32 application. It calls popen() from msvcrt.dll, and this function crashes with a SEGV, as soon as cygcheck tries to run cygrunsrv --version. What's strange is that two prior calls to popen("id.exe") work fine. Even if I omit them, popen crashes if it's called for cygrunsrv. I have no explanation for this.
