A colleague of mine traced the problem to if (ini_get('allow_url_fopen')) {
    enableCatchErrors();
    enableSilentErrors();
    $ctx=stream_context_create(array('http'=>array('timeout' => 5)));   <==== CRASH HERE
    $ctx=getStreamContext(5);
    $json = file_get_contents($urlPlugins,false,$ctx);
    disableCatchErrors();
    disableSilentErrors();
  }
  if (!$json) return $result;

which caused the coredump.
