Subject: renderer: fix memory leak in vertex elements state create
|
|
|
|
Reported-by: Li Qiang
|
|
Free the vertex array in error path.
|
|
This was introduced by this commit:
|
|
renderer: fix heap overflow in vertex elements state create.
|
|
|
|
I rewrote the code to not require the allocation in the first
|
|
place if we have an error, seems nicer.
