Subject: Fix symlink-bad-length test for 64-bit architectures.
|
|
|
|
* src/util.c: Return non-zero exit code if EOF is hit prematurely.
|
|
* tests/symlink-bad-length.at: Revert to original archive: there's
|
|
no use testing for recovery, because that depends on the host
|
|
architecture. Don't test for exit code as well (same reason).
|
|
Account for eventual warning messages.
