Improve support for memory leak detection
|
|
|
9dc0ea4 |
|
|
|
9dc0ea4 |
When building with the address sanitizer on, free some more resources before
|
|
|
9dc0ea4 |
exiting. (This is unnecessary when not looking for memory leaks.)
|
|
|
9dc0ea4 |
* src/patch.c (init_files_to_delete): Add dispose function for freeing
|
|
|
9dc0ea4 |
filenames.
