C++ crash on getting pointer -

i'm guessing it's leading nowhere, null pointer or something, i'm checking beforehand

both of these snippets crash:

//snippet 1 dword *address = (dword*)(base + 0x54);  if (address)     address = (dword*)(*address + 0xc);  if (address)     address = (dword*)(*address + 0x8);   //crashes here   //snippet 2 dword address = *(dword*)(base + 0x54);  if (address)     address = *(dword*)(address + 0xc);  if (address)     address = *(dword*)(address + 0x8);   //crashes here 

am doing wrong? in advance

access violation!

you're touching parts of memory forbidden program. dereferencing pointer points unknown place undefined behavior.
