HP WDB 5.7 Release Notes

The debugger displays the following error message while attempting to attach to such a
process:
Attaching to process <pid> failed.
Hint: Check if this process is already being traced by another
gdb or other ttrace tools like caliper and tusc.
Hint: Check whether program is on an NFS-mounted file-system.
If so,you will need to mount the file system with the "nointr"
option with mount(1) or make a local copy of the program to
resolve this problem.
• GDB reports an incorrect stack trace after dlclose or shl_unload, and a subsequent
dlopen or shl_load
The librtc.[sl|so] runtime library reports an incorrect stack trace after a dlclose or
shl_unload, and a subsequent dlopen or shl_load. The leaks are displayed erroneously
when the memory address range overlaps between the newly loaded shared library, and
the recently unloaded shared library.
Workaround: Place a breakpoint at dlclose or shl_unload, and enter the info leaks
command to view the leaks accurately when a shared library is unloaded.
• When displaying information about floating point registers, GDB does not display whether
the register holds a NaT value or not.
