vmlSetMode is not working

Hello,

I wanted to use the function vmlSetMode for c++ but the input parameter is ignored for all possible inputs. For example:

unsigned int x = vmlSetMode(VML_ERRMODE_IGNORE);
unsigned int y = vmlGetMode();

The value of x seems to be random (0xffffb2c0, 0xffffaa36, ...) and y is always different from VML_ERRMODE_IGNORE and equals x.

System infos: RedHat, Netbeans 8.0.2, Parallel Studio Composer 2016.

 Does anybody have an idea?

Thanks
