Subject: [PATCH] nms_adpcm: fix int overflow in sf.frames calc
|
|
|
|
When calculating sf.frames from the blocks_total PNMS variable, it is
|
|
theoretically possible to overflow the blocks_total int boundaries,
|
|
leading to undefined behavior.
|
|
|
|
Cast blocks_total to a long-sized sf_count_t before the calculation, to
|
|
provide it with enough numeric space and because that is the final
|
|
typing regardless.
