Subject: [PATCH] Make sure that we don't dereference NULL
|
||
|
|
|
||
|
|
The code was actually safe, because b should
|
||
|
|
never be null, because if rvalue is empty, a different
|
||
|
|
branch is taken. But we *do* check for NULL in the
|
||
|
|
loop above, so it's better to also check here for symmetry.
