Bus error of gdb 5.0 with MIPS patch

[Jun Sun <jsun@mvista.com>]

Hi,

I started to play with gdb 5.0 + the MIPS patch at
http://www.ds2.pg.gda.pl/~macro/gdb-5.0/, but I am having a bus error if
I want to do 'next step'.  Setting breakpoints and continuing running
seem to be fine.

The gdb 4.17 rpm from oss.sgi.com does not have this problem.

Any idea?

P.S., Does anybody know how to fix "tcsetpgrp ..." error?
