Title:
  gdb crashed with SIGSEGV in splay_tree_remove()

Status in “gdb” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: gdb

  Hm. GDB didn't crash, it burned CPU and an attached strace didn't show
  any activity. Totem crashed and apport attached GDB to the crashing
  process. GDB then hogged the CPU for >20 minutes before I pkill
  -SEGVed gdb.
