From: Wentao_Liang <Wentao_Liang_g@163.com>
A memory chunk is allocated with g_new0() and assigned to the variable
'storage'. However, if the branch takes true, there will be only an
error report but not a free operation for 'storage' before function
returns. As a result, a memory leak bug is triggered.
Use g_autofree to fix the issue.
