Subject: Always check the number of coefficients
|
||
|
|
|
||
|
|
When building the library with NDEBUG, asserts are eliminated
|
||
|
|
so it's better to always check that the number of coefficients
|
||
|
|
is inside the array range.
|
||
|
|
|
||
|
|
This fixes the 00191-audiofile-indexoob issue in #41
