static watchpoints may cause memory probes to fail.
Facility: DEBUG, VMS Debugger
Explanation: The debugger implements static watchpoints by write-
protecting the page containing the variable being watched. A
system service that writes to user memory will probe for write
access before executing the write. With static watchpoints set,
if such a system service probes a write-protected page, the
system service will return SS$_ACCVIO instead of successfully
completing. This also holds for user written routines that
probe memory for write access. On VAX, the debugger could work
around the problem with system services via system service
interception. On Alpha AXP this system service interception is
not yet implemented.
User Action: If this potential behavior change is not acceptable,
reset the watchpoint without the /STATIC qualifier.
