Multi Index Container ordered index - infinte loop when advancing iterator which is the end iterator

[Avi Revivo]

Hi All,

Is this a known issue that if due to a wrong usage the .end iterator is advanced there is an infinte loop?

Thanks in advance,
Avi Revivo

Advancing an end iterator invokes undefined behavior.

Hello Avi,

As Felipe remarks, advancing end() is illegal, and anything
can happen if you perform an illegal operation. You can detect
this and other wrong usages of Boost.MultiIndex in a more
convenient fashion by using the provided safe mode:
