Subject: [PATCH] Fix integer overflow during multiplication with
|
||||
realtic_clock_rate (#476)
|
||||
|
||||
When the program has run for about 26 minutes and SDL_GetTicks has
|
||||
accrued a reasonably large value, multiplication by realtic_clock_rate
|
||||
overflows "int" on contemporary platforms, manifesting in jagged
|
||||
motion.
|
||||
|
||||
Fixes: v2.6.1um-29-ga7bafe07
|
||||
Closes #471
