Programming Release Notes
6.9 Debugger
6.9.23 Source View Update
V7.3
In previous versions, the DECwindows Motif interface to the debugger did not
correctly update the source view on a return step command from a subroutine call
when the calling routine was in a different source module. This problem has been
corrected.
6.9.24 SHOW SYMBOL IN Clause
V7.3
The ability of the debugger to set modules dynamically has been improved.
6.9.25 Corrupted Stack Errors (Alpha Only)
V7.3
On Alpha systems, some recent compilers introduce certain stack errors. If
previous versions of the debugger encounter these errors while program execution
is suspended at a breakpoint, a STEP or other resume command can result in the
following error:
%DEBUG-W-NORESUME, unable to resume execution, stack or PC corrupted.
This problem has been corrected, and you should upgrade the compiler that
causes the corrupt stack.
6.9.26 Just-in-Time Debugging
V7.3
When attempting just-in-time debugging (for example, when DBG$TRACE
is defined as SYS$SHARE:DEBUG.EXE), previous versions of the debugger
sometimes fail. This has been corrected.
6.9.27 Debugger Does Not Support Previous Version of Client/Server Interface
V7.3
The OpenVMS Version 7.3 debugger does not support previous versions of the
client/server interface. You must install the client/server interface found in the
kit on the distribution media, as identified in the following table:
CPU Operating System Client Kit
Intel Microsoft Windows 95,
98
[DEBUG_CLIENTS011.KIT]DEBUGX86011.EXE
Intel Microsoft Windows NT,
2000
[DEBUG_CLIENTS011.KIT]DEBUGX86011.EXE
Alpha Microsoft Windows NT [DEBUG_CLIENTS011.KIT]DEBUGALPHA011.EXE
These client kits are self-extracting .EXE files.
Once the appropriate executable file has been transferred to the PC, you can
run the file to install the debug client on the PC. The InstallShield installation
procedure guides you through the installation.
By default, the debug client is installed in the \Program Files\OpenVMS Debugger
folder. You can also click Browse to select an alternate location.
