Bus error

Can also reproduce with @maleadt's build on aa05c98.

The error happens on the constructor of Crayons.Crayon(). It also happens with @code_llvm Crayon() or @code_typed, without actually running the code. A debug+asserts build of Julia didn't give any extra information.

Edit: note, I get this only on this BananaPi BPI-F3 board:

I couldn't reproduce the bus error on other machines.
