savedpc is always NULL for C functions. But the previous check
(if (!isLua(ci))...) should return in that case. Otherwise it is NULL
just when the function in being called. But it is initialized before
'ci' is incremented to point to it (see luaD_precall).

Did you use valgrind or something similar (mainly to check whether
savedpc is actually NULL or an uninitialized value that happens to
be NULL)?
