- When determining the caller of a function in the XS version, use
  Perl's caller() function rather than CopSTASHPV. The caller()
  function apparently ignores the DB package, whereas the latter
  doesn't. This caused validate_options to be ignored when running
  under profiling (and probably the debugger as well). Thanks to Jeff
  Weisberg for pointing this out.
