Наврал... Просто проработало дольше, чем обычно...

Пройти по первой ссылке, внезапно приведённой ногой и включить в системе запись core dump'ов, видимо, не судьба?

Собрал с "-O0 -pipe -g -ggdb" и "nostrip"...

дольше анализирует, но вывод не меняется...

Наверное, хочет оповещение какое-то в трее показать...
