i see some of the addresses mentioned there belong to some of libsidplayfp's functions as well, so should we open a similar issue over there as well?

i also noticed more of those are being shown in valgrind's output from my fork which's currently having that segmentation fault problem as well (in an attempt to implement the new player API on it)
EDIT: nevermind just fixed that now xd
