This is on OSX 10.12.6

i met the same question.
in my case it arised from build.c, line 259
strcpy(o->lineorders[lcnt].opriority,o->opriority);
sometimes lineorder.opriority exceeds the limit：MAXAGG_LEN

in shared.h, line 120, change MAXAGG_LEN from 10 to 32,
#define MAXAGG_LEN 32 /* max component length for a agg str */
and it works

[Alan Bernstein]

This worked for me as well.

I experienced a similar crash, and this fix worked for me as well. Thanks so much!
