Unexpected access violation

$

I am using the latest: Fortran Compiler XE 14.0.3.202

The program I am working on has started unexpectedly crashing when compiled in optimized release mode.  However, when compiled in debug mode, there are no errors or warnings.  I have spent a day debugging, and I was able to isolate the portion of the code where the problem occurs.  This code is very unstable, and doing a trivial change can make the problem go away.

Attached is the source code, project, and output BuildLog files.  When compiled in release mode, the program crashes with:

forrtl: severe (157): Program Exception - access violation
