From c94736a27f89bfc268aed0de7264deecdc136a58 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 30 Jul 2009 17:38:15 -0700 Subject: merge-recursive: don't segfault while handling rename clashes When a branch moves A to B while the other branch created B (or moved C to B), the code tried to rename one of them to B~something to preserve both versions, and failed to register temporary resolution for the original path B at stage#0 during virtual ancestor computation. This left the index in unmerged state and caused a segfault. A better solution is to merge these two versions of B's in place and use the (potentially conflicting) result as the intermediate merge result in the virtual ancestor.
