Hi,

Since yesterday one test marked as compile-fail is now reported as a 
failure on the regression tests page.

It's the test: rtree_values_invalid
on the page: 
http://www.boost.org/development/tests/develop/developer/geometry-index.html

Surprisingly other tests aren't.
see e.g.: geographic_custom_point_with_wrong_units
on the page: 
http://www.boost.org/development/tests/develop/developer/geometry.html

They seem to be defined the same way in the Jamfile:
https://github.com/boostorg/geometry/blob/develop/index/test/rtree/Jamfile.v2
https://github.com/boostorg/geometry/blob/develop/test/point_concept/Jamfile.v2

AFAIS the oldest run when it failed was of the runner: 
teeks99-03c-Ubuntu12.04-64 on Sat, 10 Jan 2015 02:05:44.
On Fri, 09 Jan 2015 18:36:55 (teeks99-08b-win2012R2-64on64) everything 
was ok.

Furthermore when run locally it's also reported as a failure. Some time 
ago of course "(failed-as-expected)" message was printed instead.
Do you have any idea what may be wrong?

Regards,
Adam
