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

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,
