I don't break into the debugger, my program breaks during normal execution.

It is clear by inspection that item_version is not initialised if
3 >= ar.get_library_version()
and then used as an argument to ifunc.

As a minimum/temporary solution I'd advise that the line:
unsigned int item_version;
is replaced by
unsigned int item_version = 0;
or put an else clause in the if statement.

Perhaps these should explicitly be turned on by boost developers and be
left off by default so users don't get caught by other problems like this.
