Logic addresses (LA) shall be only used for heap objects. Other addresses, like stack or IP, shall be traced with the virtual address instead.
Exit if the heap tracking seems to be corrupted. This is the case, if a heap object exists, but has no valid entry.
hashmap stored prior created hashs within a vector. The last created hash was used to create a new unique hash. hashmap now only counts the occurences of each hash and uses this counter to diversify the created hashes.
Using object size as input for the logical address hash calculation leads to different hashes even if an allocation was called from the same calling location. We don't need this diversification, as the counter already leads to different hashes if needed.
Callsite is redundant information as the callstack contains the callsite.
Allocatios have to be always recorded, as the pintool converts each virtual memory address into a logical address. If it fails to do so it will trigger a fault. Therefore the pintool needs to be aware about all allocated memory objects.
For libc at other installed libaries a separate package can be installed to access debug symbols. But for this a separate elffile is stored with an arbitrary name. gdb does automagically detect this and loads the correct files. If nm fails to load any symbols, gdb is used as a fallback to find the debug elffile.
