Subject: [PATCH] block: Fix regression for MinGW (assertion caused by short
|
|
string)
|
|
|
|
The local string tmp_filename is passed to function get_tmp_filename
|
|
which expects a string with minimum size MAX_PATH for w32 hosts.
|
|
|
|
MAX_PATH is 260 and PATH_MAX is 259, so tmp_filename was too short.
|
|
|
|
Commit eba25057b9a5e19d10ace2bc7716667a31297169 introduced this
|
|
regression.
