Description
sage: C = HammingCode(5, GF(2)) sage: C.automorphism_group_binary_code() Exception MemoryError: MemoryError('Memory.',) in 'sage.coding.binary_code.BinaryCodeClassifier.aut_gp_and_can_label' ignored ------------------------------------------------------------ Unhandled SIGSEGV: A segmentation fault occurred in Sage. This probably occurred because a *compiled* component of Sage has a bug in it (typically accessing invalid memory) or is not properly wrapped with _sig_on, _sig_off. You might want to run Sage under gdb with 'sage -gdb' to debug this. Sage will now terminate (sorry). ------------------------------------------------------------

Also, as Thomas points out we should be checking whether to use the dual code...
