Setarea breakpoint în încărcător dinamic pe iOS Simulator

voturi

Alerg într - o problemă în cazul în care încărcătorul de dinamic este crashing în dyld_sim`memcmp. Am încercat să determine care biblioteca a fost de încărcare la momentul respectiv , dar stiva pare corupt (cel puțin, registrele de argument nu sunt disponibile).

Așa că încerc să stabilească un punct de întrerupere în încărcătorul (în continuare până stiva), dar punctele de întrerupere în dinamica încărcător nu par să băț. De asemenea, am încercat setarea de breakpoint simbolice, dar cei care nu declanșează. Nu știu dacă este pentru că eu sunt ortografie greșit (de exemplu, „dyld :: sarcină“ nu a funcționat).

Orice idei pentru ceea ce eu pot încerca?
