 And it should (assuming ptrace(2) gets things right) -- if what you say 
is true, then it's a bug rather than a deliberate design decision.  To add 
some irony, MIPS GDB is always 64-bit internally.

 Try a newer version though -- GDB 7.2 has been out for a (short) while 
now.  You're missing 2.5 years of development.  If still unsuccessful with 
a pristine release from ftp.gnu.org, then file a bug report at
