Subject: [PATCH] Improve support for memory leak detection
|
||
|
|
|
||
|
|
When building with the address sanitizer on, free some more resources before
|
||
|
|
exiting. (This is unnecessary when not looking for memory leaks.)
|
||
|
|
* src/patch.c (init_files_to_delete): Add dispose function for freeing
|
||
|
|
filenames.
