Subject: Fix crash when handling the ALRM signal.
X-Git-Tag: release-1.1pre3~118
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=bce177767d521b47efd458c5cd570959a98d940d

Fix crash when handling the ALRM signal.

In retry() the function do_outgoing_connection() is called, which can delete
items from the connection_tree, so when walking the tree we must first save the
pointer to the next item.
