Each time I saw that kind of problem on OpenVMS, it was a
"double deallocation" issue. This is an application error.
Example:
A := new Something;
B := A;
Free (A);
Free (B); -- at this point the zone gets corrupted
After that, I have seen many different kinds of behavior.
This does not mean that the specific datum you mentioned
is the culprit. It may be any other in the same zone
("collection" in Ada words).
Since you are on OpenVMS, I suggest that you use the
"heap analyzer" (see the VMS debugger manual). This
is a brilliant tool.
