Fortran 90 on Itanium®-based systems running HP-UX 11i v2 or HP-UX 11i v3, and HP 9000
systems running HP-UX 11i v1, HP-UX 11i v2, or HP-UX 11i v3.

What is new in this version
This release of HP WDB 6.3 includes the following new features:
• HP WDB GUI supports Intel® Itanium® 9500 Processor Series.
• A rotating bar is displayed when info leaks or info dangling commands are executed
in interactive session of WDB. This shows that WDB is busy in processing and is not in a hung
state.
• More intuitive leak reports in interactive mode
WDB now displays more intuitive messages in the leak reports during an interactive session.
• rtcconfig file support for attach mode
librtc library users can now setup the configuration file rtcconfig for attach mode in the
same way as batch mode. For more information about debugging in attach mode, see
Debugging Dynamic Memory Usage Errors Using HP WDB.
• Global rtcconfig file support
librtc library is enhanced to read global rtcconfig file by default during batch mode
and attach mode. Therefore, you can eliminate the need for creating the rtcconfig file for
default settings. For more information about debugging in attach mode, see Debugging
Dynamic Memory Usage Errors Using HP WDB.
NOTE: The global rtcconfig file is installed at predefined location along with HP WDB.
Patches and defect fixes in HP WDB 6.3
The following defects are fixed in HP WDB 6.3:
• WDB now supports two new registers AR.RUC and CR.IIB.
• WDB cannot recognize function of shared library if the executable has same name as the
function.
• WDB 6.1 loops infinitely when top frame is a signal handler caller.
• WDB passes -p option when invoking sentinel, as the sentinel does not recognize this option.
Due to this HP WDB is unable to perform crashdebug functionality when attaching a process.
• When WDB uses libpthread_tr and rtc in the same executable complied with aCC
compiler, WDB results in a crash.
• WDB displays incorrect symbol name when Info symbol command does not work on static
variables.
• WDB displays incomplete backtrace when stopped in a native code frame in JNI program.
