Subject: [PATCH] Fix Storable segfaults.
|
|
|
|
Fix a null pointed dereference segfault in storable when the
|
|
retrieve_code logic was unable to read the string that contained
|
|
the code.
|
|
|
|
Also fix several locations where retrieve_other was called with a
|
|
null context pointer. This also resulted in a null pointer
|
|
dereference.
