There are probably multiple differences.

And a lot of code triggering the problems are probably rather bad code.
But the expectation for VMS x86-64 is 99.9999% compatibility not 99%
compatibility.

If I remember correctly then the example given in one of these threads
were a Fortran common block where some part of the data was initialized
in some code and other part of the data was initialized in other code.
