[Info-vax] Debugging shareable images on Integrity

[jcwoman1963 at hotmail.com]

Hi,
  I have a routine that's embedded in a shareable image that I need to
step through in the debugger in order to locate a problem.  I've been
able to do this with the same code on Alphas with no problem, but it
appears that the debugger behavior has changed a little on Integrity,
but I'm not sure how to compensate for it.  Here is what I mean:

  My image is installed with the INSTALL/SHARE command. No priv's or
other installer parameters.  The shareable modules and my application
are written in Macro.  I compile and link it and my application that
calls it with the debugger.  I can verify this because the image size
is larger.  Also, it does display the sharable image source code in
the debugger.  But, when I try to step through the module's source
code, it just displays the same line of code over and over again.

  More precisely here is what I'm doing:

Install the shareable.  Run my application in the debugger, and

SET IMAGE SHRLIB
SET MODULE HISLIB
SET BREAK HIS_SFHR
GO

Then when I send the application command and it hits the breakpoint,
it does break at the .ENTRY and displays the source of the HIS_SFHR
module.  Great!  From this point on, step does nothing but display
the .ENTRY line over and over again.  If I set another breakpoint
inside the module, say the next executable line and type GO, it does
NOT stop at the breakpoint.

I've been perusing the Debugger help menus with no ideas so far.  I've
checked that my STEP is defined as:

step type: nosource, nosilent, by line, over routine calls.

Even when I change the step type to "source", I get the same
behavior.  What am I missing?  (Also, what details have I forgotten to
include here to help you guys help me?)
