Crash using amatch

[martnst]

Hi,

using the amatch engine significantly speeds up my matching.

Unfortunately it is not stable (at least for me).

I ofter get this crash when using to amatch:

.../ruby/2.1.0/gems/fuzzy_match-2.1.0/lib/fuzzy_match/score/amatch.rb:12: [BUG] Segmentation fault at 0x00000000000008

This part of the crash log might be of some interest … I don't know:

This problem is caused by an external dependency, and an issue already exists for it upstream.

...but it looks like you saw that?
