[Bug tree-optimization/67601] Vectorization of loop causes aligned access to possibly unaligned address

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67601 --- Comment #2 from Richard Biener --- You are invoking undefined behavior because you are dereferencing table in table[i]+=fTracksPointer; and table is not aligned according to its type (Long64_t).
