Thanks again, Peter.
I did as you suggested and the result works pretty well.
Prompted by the diagnostic from gdb/utils.c, I also added
MMALLOC_CFLAGS = -I$(MMALLOC_SRC) -DMMCHECK_FORCE=1
in i386sol2.mh.
The only thing that's a little odd is that now I get this at startup:
[GDB will not be able to debug user-mode threads: ld.so.1: gdb: fatal: relocation error: symbol not found: ps_lgetLDT: referenced in /usr/lib/libthread_db.so.1]
and this when I `quit':
(gdb) q
gdb internal error: Memory corruption
Quit
[Exit 131 (SIGQUIT)]
