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.
