Reed Mueller code crashing

[MathieuDutSik]

In Sage 9.5.rc1, the following command causes a crash:

sage: C = codes.BinaryReedMullerCode(16, 32)
------------------------------------------------------------------------
(no backtrace available)
------------------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.
------------------------------------------------------------------------
.../src/bin/sage-python: line 2: 60716 Segmentation fault: 11  sage -python "$@"

In case the input is invalid, an error
would be preferable to a crash.
