Comment (by csnover):

 I spent some time looking at this today and I am not entirely sure what is
 going on yet. The kMulDiv and kSinMult/kTimesSin implementations in
 ScummVM are not accurate to the original interpreter and return slightly
 different values pretty frequently, but I implemented some fully reversed
 versions of these functions (SinMult is definitely an interesting edge-
 case, since the original interpreter does an out-of-bounds read into the
 value table for atan when degrees = 90) and these implementation
 differences don’t appear to be the cause of the trouble. So, more
 investigation is needed.
