This section describes the following new features in this version of HP WDB:

• “Reporting Files Open by an Application” (page 4)

• “Improved Understanding of Scope Resolution Operator in gdb Expressions”

(page 4)

• “More Intuitive Leak Reports” (page 5)

• “Debugging with Debug Information Available In the Side Debug File” (page 5)

Reporting Files Open by an Application

With this feature, you can obtain a report containing the list of file descriptors

corresponding to files open by an application at the point of its exit. The report not only

provides you the name and type of those files, but also details like backtrace and function

names at the point of the files being opened. This enables you to identify potential file

descriptor leaks in the application.

NOTE: This feature is currently supported only on HP Integrity systems.

Improved Understanding of Scope Resolution Operator in gdb Expressions

When you debug Fortran applications the following syntax is supported while printing

variables in gdb expressions:

where 'procedure' may be a function or a subroutine.
