GitHub Issue #1026 reported a crash during configuration check for the following example config: backend 0 server 0 0 server 0 0 HAProxy crashed in srv_set_addr_desc() due to a NULL pointer dereference caused by `sa2str` returning NULL for an `AF_UNSPEC` address (`0`). Check to make sure the address key is non-null before using it for comparison or inserting it into the tree. The crash was introduced in commit 92149f9a8 ("MEDIUM: stick-tables: Add srvkey option to stick-table") which not in any released version so no backport is needed.
