* h8300-tdep.c (h8300_frame_init_saved_regs) : Check whether frame base
is null.
Are you sure this patch is against 6.1 or a current GDB? The function
h8300_frame_init_saved_regs has a void return type.
Also, you might want to read over:
Post GDB 6.2, require new frame code
http://sources.redhat.com/ml/gdb/2004-06/msg00199.html
As this will affect the h8/300.
