Subject: [PATCH] video_output/xcb: fix memory-leak in ReleaseDrawable
|
||
|
|
|
||
|
|
The problem with the previous implementation is that "n" will never
|
||
|
|
be equal to 0 at the relevant part of the code (given the
|
||
|
|
unconditional pre-increment a few lines earlier).
|
||
|
|
|
||
|
|
These changes fixes the issue by freeing the allocated memory if the
|
||
|
|
first element of "used" is NULL (meaning that there are no more
|
||
|
|
entities referred to by it).
|
||
|
|
|
||
|
|
fixes #17112
|
||
|
|
fixes #17293
