Subject: [PATCH] Fix Segv on unknown address error flagged by fuzzer test.
|
|
|
|
|
|
|
|
|
|
The error is thrown when the destructor tries to free pointer memory.
|
|
|
|
|
This is happening for cases where the pointer was not initialized. Initializing it to a default value fixes the error.
|
|
|

Test: Build mtp_host_property_fuzzer and run on the target device
