Subject: [PATCH] die_unwind(): global destruction
|
|
MIME-Version: 1.0

Fix #18063
|
|
|
|
During global destruction make sure we preserve
|
|
the string by using mortalcopy.
|
|
|
|
This is an update on 8c86f0238ecb5f32c2e7fba36e3edfdb54069068
|
|
change which avoided sv_mortalcopy in favor of sv_2mortal.
