[Rtk-users] RTK + Cuda 9 + gcc 6.4 segfaults

[Mathis Hoffmann]

Ok, I was a bit early with the conclusion that this is Cuda related. 
Seems not. The only tests that pass are:
- rtkappsimulatedgeometrytest
- rtkappprojectshepploganphantomtest
- rtkwaveletstest
- rtkargsinfomanagertest

Kind regards
Mathis Hoffmann
