I'm not surprised. The check for `replace-buffer-in-windows' does
pretty much the same as Eli's approach. You just don't have to run
Emacs in the debugger in order to use it.
Maybe try now:
diff --git a/src/buffer.c b/src/buffer.c
index 8e33162989..9ca5731bcf 100644
--- a/src/buffer.c
+++ b/src/buffer.c

+ error ("Selecting deleted buffer");
+
old_buf = current_buffer;
current_buffer = b;
last_known_column_point = -1; /* Invalidate indentation cache. */
