Abort when cleaning up fails
|
|
|
796689 |
|
|
|
796689 |
When a fatal error triggers during cleanup, another attempt will be made to
|
|
|
796689 |
clean up, which will likely lead to the same fatal error. So instead, bail out
|
|
|
796689 |
when that happens.
|
|
|
796689 |
src/patch.c (cleanup): Bail out when called recursively.
|
|
|
796689 |
(main): There is no need to call output_files() before cleanup() as cleanup()
|
|
|
796689 |
already does that.
