Subject: [PATCH] Always check asprintf return code
|
|
|
|
There is a small number of the places in sources where we don't check
|
|
asprintf() return code and assume that after error the function
|
|
returns NULL pointer via the first argument. That's wrong, after
|
|
error the content of pointer is undefined.
