HP WDB 6.2 Release Notes Announcement HP Wildebeest Debugger (WDB) 6.2 is an HP-supported implementation of the open source debugger GDB. It supports source-level debugging of programs written in HP C, HP aC++, and 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. This document discusses the most recent product information for HP WDB 6.2.
Smarter Printing of Function Pointers WDB is made smarter now in printing the function pointers. It now decodes extra level of indirection for the programmer’s convenience. More Intuitive Leak Reports A note will be appended to every memory debugging report providing more details for function names displayed as ???. Debugging with Debug Information Available In the Side Debug File From version B.12.56, the HP-UX/Integrity linker has added an option +dbgfile .
• Gdb does not detect core file and executable mismatch and sometimes crashes in dld. • User disabled watchpoint gets wrongly re-enabled automatically. • Gdb sometimes wrongly gives out a message that the target program received SIGSEGV, when a misaligned load is retired and a wacthpoint is set. • Gdb sometimes crashes after watchpoint is set on local variable.
workaround is to use the packcore command to obtain the core file and the involved load modules into the system on which the debugging occurs.
This occurs when GDB attempts a command line call on an already overflowing thread stack. Mixed Mode Debugging Following are known issues in mixed mode debugging: • Listing of registers currently in use for PA-RISC 32-bit shared library frames causes the unswizzled 32-bit values to be displayed. • Clicking on the registers tab for a PA-RISC frame in the WDB-GUI results in incorrect register information being displayed. Alternatively, execute the info reg command at the gdb prompt in the Commands tab.
pre-loaded, the debugger obtains the thread-error information in the batch mode for exec-ed application. • HP WDB cannot execute both batch mode thread check and batch mode heap check together. If the rtcconfig file has both entries, then batch heap check overrides the batch thread check. Mixed Mode Debugging The following are not supported for mixed mode debugging: • Placing a breakpoint on a PA-RISC library.
