==3702799==ABORTING

Non-ASAN builds don't crash for me, but return an unexpected (or at least inconsistent) warning ER_JSON_SYNTAX:

10.3 049811ec

 
SELECT JSON_MERGE_PATCH(NULL,1,JSON_MERGE('{"foo":"bar"}','{"baz":"qux"}'));
 
JSON_MERGE_PATCH(NULL,1,JSON_MERGE('{"foo":"bar"}','{"baz":"qux"}'))
 
NULL
 
Warnings:
 
Warning	4038	Syntax error in JSON text in argument 1 to function 'json_merge_patch' at position 1

It is unexpected because the argument 1 is NULL, there is nothing syntactically incorrect about it; and inconsistent because this works without a warning:

SELECT JSON_MERGE_PATCH(NULL,JSON_MERGE('{"foo":"bar"}','{"baz":"qux"}'));
 
JSON_MERGE_PATCH(NULL,JSON_MERGE('{"foo":"bar"}','{"baz":"qux"}'))
 
NULL

None is reproducible with JSON_MERGE_PRESERVE.
