Very intermittent segmentation fault with boost::multiprecision

Team,

Trying to get to the root of a very intermittent seg fault in my program.
Here's the snipped (not able to reproduce) as the section of code is part
of a callback and I'm not sure how to reproduce it.  Here's the tickPrice
method and the trace from gdb is below that ... any thoughts?
