Backtrace from superfastmatch search client when using quoted text

[dvogel]

I've loaded a bunch of documents. Searched for one of the loaded documents and I get these matches:

$ ./superfastmatch-linux search 111/s/s62-111-is.txt
Doc:s999-111-is.txt (1,1)   Left:      857  Right:     1096 Length:      170    Text: Be it enacted by the Senate and House of Representatives ...

Successes: 0     Failures:0

However, I get a backtrace when I search for the first match as quoted text:
