[Qemu-stable] [PATCH 28/43] block: Fix regression for MinGW (assertion caused by short string) |
Date: |

From: Stefan Weil <address@hidden>
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.
