Probably it's related to a new History datatype.

It's hard to say what caused the crash. It happened inside of sqlite code

        while( 1 /*exit-by-break*/ ){
          zPayload[--i] = (u8)(v&0xFF);
          if( i==0 ) break;
          v >>= 8;
        }

So marking needs-more-info, maybe we'll get some more useful information or STR.
