Error when performing "LCALCEPS = .TRUE." calculations

Hi VASP bug forum,

"LCALCEPS= .TRUE." calculations to determine the dielectric constant cause vasp to crash at the beginning of the 3rd electronic self consistency loop, corresponding to the application of a finite electric field. This error occurs on multiple machines with different architectures, with vasp 5.3.3 compiled with O1 optimization (also crashes with O3). The error occurs with a 16 atom unit cell oxide, but I am able to run the NaF example in the vasp manual with no problems. Any help would be appreciated, thanks!

Here is the text from the crash:
