Matlab example2 assertion failed!

[zishun]

When the dll built with debug configuration is used, Matlab example2 pops up a window saying that

“Assertion failed！ geodesic_algorithm_exact.h Line:1166 
Expression:p->start() < p->stop()” 

Reasonable results can still be obtained if you click the button Ignore.
If the dll built with release is used, Matlab will crash.

Is it necessary to have geodesic_algorithm_exact.h Line:1166?

assert(p->start() < p->stop());

Of course it is a straightforward workaround to comment out that line, which has been tested.
