Did anyone experience problems when using expf() from math.h in VisualDSP++ 5.1.2?

Hello,

 

in my company I recently got an update on VisualDSP++ v5.1.2 (from 5.0 Update 10.1). With the new version I encounter some problems using the exponential function in my code for a SHARC ADSP-21469. With the old version, the code runs as intended, but with the new version the DSP stops shortly after booting.

I managed to get it sorted to the point that the code works when I comment the exponential function out. No matter where I try to use it, after re-adding an exponential function (even as float test = exp(1.0f); ) the dsp starts refusing to work.

 

To be honest, I have no idea what could cause this problem. A corrupted file during installation of VisualDSP++ maybe?

 

I wanted to see if there is someone with an idea for me before handing my computer to the it department for reinstalling the software.

 

Thanks in advance and best regards,

 

Daniel
