Sparc64 Solaris status

[Paul Hilfinger]

Some months ago, I asked about the status of GDB5 on 64-bit Solaris
host/target combinations.  I interpreted the reply as "it works,
doesn't it?"  It seems not to, but the behavior I get is such an
immediate show-stopper that it makes me believe that the problem must
be extremely sensitive to configuration (i.e., I have the wrong one
and my respondants don't).  I have also found archived mail from
people experiencing the same difficulty that I do.

A recent (20 Jan 2001) version of GDB 5 sources configured on an
UltraSparc (sun4u sparc SUNW,Ultra-5_10) running Solaris 2.7  with

           .../configure sparc64-sun-solaris2.7

compiled using GCC 2.8.1 when run on an executable compiled with

         cc -xarch=v9 -g -o test64 test64.c

displays the following anomalies:

     b main
    Cannot access memory at address 0x0    <<<<????
    (gdb) b test64.c:8
    Breakpoint 1 at 0xc: file test64.c, line 8.
    (gdb) run
    Starting program: /export/home/users/hilfingr/gdb/test64 
    procfs:3887 -- process not stopped.    <<<< ?????
    procfs: ...giving up...

Any assistance or comments gratefully received.
