Subject: [PATCH 1/6] vcl: assign nullptr after deleting
|
|
|
135360 |
|
|
|
135360 |
In the preinit stage, the VCL initialization is done by the parent process
|
|
|
135360 |
and when the lo_startmain thread de-initialize the VCL, some services are
|
|
|
135360 |
disposed early, and it causes segmentation violation.
|
|
|
135360 |
|
|
|
135360 |
So it is ensured that pointers to service objetcs is set nullptr after
|
|
|
135360 |
deleting.
|
|
