2014.2 Vivado HLS - Internal error occurs without detailed information.


During C Synthesis, an Internal error occurs without detailed information.


This can occur when the code accesses an array with a negative address. 

The address is out of range and this will cause un-predictable issues.

In some cases the crash cannot be re-produced, even though no change is made to the design.

The best practice is to do C simulation to verify the code before moving forward.
