From 6738c8194286fa0017f72cb57628dcae9ec07b27 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 8 Nov 2007 01:38:12 -0800 Subject: send-pack: segfault fix on forced push When pushing to overwrite a ref that points at a commit we do not even have, the recent "terse push" patch tried to get a unique abbreviation for the non-existent (from our point of view) object, which resulted in strcpy(buf, NULL) and segfaulted.
