From 2eb26d8454de77f45bbbfc32eed2a6c3133fe963 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Sat, 26 Aug 2006 22:38:02 -0400 Subject: [PATCH] Fixed GPF in fast-import caused by unterminated linked list. fast-import was encounting a GPF when it ran out of free tree_entry objects but didn't know this was the cause because the last tree_entry wasn't terminated with a NULL pointer. The missing NULL pointer occurred when we allocated additional entries via xmalloc but didn't set the last tree_entry's "next" pointer to NULL. Signed-off-by: Shawn O.
