             Bug #: 15451
           Summary: Can't locate registers loading Sparc core in threaded
                    program.
           Product: gdb
           Version: 7.6
            Status: NEW
          Severity: normal
          Priority: P2
         Component: corefiles
        AssignedTo: unassigned@sourceware.org
        ReportedBy: nospampeeps@yahoo.com
    Classification: Unclassified


Loading core file fails on Sparc Solaris with "warning: Couldn't find
general-purpose registers in core file." and "warning: Wrong size fpregset in
core file." warnings. Backtrace and most other functions do not work of course.

I reran the program and did a 'gcore' on the running process. I then ran gdb
and got the above errors. This GDB works on other non-threaded programs.


Process used to generate core and loading it underGDB follow:
