             Bug #: 14992
           Summary: gdb on object file produces: internal error - "Please
                    report this bug"
           Product: gdb
           Version: 7.1
            Status: NEW
          Severity: minor
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: ThomasDHowell@gmail.com
    Classification: Unclassified


I just re-installed gcc and gdb under Windows 7 Professional SP1.
The downloads were these:
mingw-w64-bin_i686-mingw_20111220.zip
x86_64-w64-mingw32-gdb-7.1.90.20100730.zip

I teach a course in which students compile C programs and examine the machine
instructions they generate.  I was testing the capability to generate and
examine x86_64 code.  The test program is rtsb.c.  It reads a command line
argument as a decimal or hex integer prints the bytes representing the argument
and its address. 

gcc -m64 -g -c rtsb.c runs and generates rtsb.o

gcc -m64 -g rtsb.c runs and generates a working executable file.
objdump runs fine on either the object file or the executable.

gdb needs to run on the executable file, not the object file, but
I typed the following line in error (should have typed just  gdb rtsb).
gdb rtsb.o   
It creates the following output.

This is not an important problem for me.  It happens only when I make a typo,
but the error message asks for a bug report, so here it is.
