sparc 32/64bit mixup?

[Dykiel, Richard]

Hello,
somebody's already got that kinf of error when running a program under gdb?

(gdb) b main
Breakpoint 1 at 0x28c2c: file ../example/db.c, line 154.(gdb) r
Starting program: /export/home2/rdykiel/build/osedb/obj/solaris/osedb 
procfs: init_inferior, get_traced_signals line 4565, /proc/6601: Value too
large for defined data type.
-----------------------------------------------

The problem occurs on a 32bit sparc running solaris2.7.
The SHELL environment variable points to a 64bit tcsh executable; this shell
is forked by gdb to run the debugged program. A truss of the run sequence
shows that gdb encounters an error Err#79 EOVERFLOW when reading the /proc
files of the tcsh process it created.

I'd like to know if it's a bug in gdb or an error in the configuration when
building gdb.
thanks

Last time I checked, a 32-bit Sparc process could not successfully
'proc' a 64-bit Sparc process.
