We are also seeing this issue, and several SimpleITK dashboards are failing
with the same error for the OS X 10.9 (since bumping to ITK 4.9) and 10.10
(since yesterday) dashboards:
https://open.cdash.org/buildSummary.php?buildid=4188623
It looks like this is essentially caused by SimpleITK being compiled with
`-std=c++11`, whereas ITK (and VXL) are not. So, there is a mismatch
between the configured definition of `VCL_CONSTEXPR` and the `
VCL_STATIC_CONST_INIT_*` macros.
For reference, VCL_CONSTEXPR was introduced here:
http://review.source.kitware.com/#/c/20386/
A proposed patch [1] is attached.
Best,
Isaiah
