Bug in Compiler or Clearwin64.DLL

The test program below, when built using FTN95 V8.1 with /debug /64, gives an illegal instruction breakpoint when run.

      program tst
      implicit none
      double precision, parameter :: one=1.d+0, three=3.d+0
      double precision machep,mepcrt
!
      machep = epsilon(machep)
      mepcrt = machep**(one/three)
      print *,mepcrt
      end     

The contents of the exception pop-up:

Within file CLEARWIN64.DLL
In  XX$DD at address 4
Within file tst.exe
in TST in line 7, at address 3b

The DLL has file version 19.5.4.6, creation date March 31, 2017, and modification date May 4, 2017.

XX$DD appears to be the routine that calculates x**y for x and y double precision.

Thanks for the feedback. This program runs OK for me so it looks like the bug has already been fixed.

'Creation date 1017'? Blimey, that makes FTN95 positively Dark Ages ! (Pre the Norman Conquest, anyway). Had Maori arrived in NZ? Were there still Moa roaming the land?

Quoted from LitusSaxonicum 'Creation date 1017'? Typo, corrected.
