Subject: [PATCH] gpt: do not leak a GPT header on an error path
|
|
|
|
* libparted/labels/gpt.c (gpt_write): Avoid a leak by freeing the
|
|
header buffer after pth_get_raw call where it's used, but before
|
|
checking whether that pth_get_raw call succeeded.
|
|
Avoid another leak in identical just 10 lines down.
|
|
Add "FIXME: caution..." comments to warn about the duplication.
