[PATCH] disassembly fixes

[Elena Zannoni <ezannoni@redhat.com>]

A few fixes for the new disassembler. I'll commit in a day or so.

2003-04-04  Elena Zannoni  <ezannoni@redhat.com>

	* disasm.c (dump_insns):  Move variables inside loop, or they will
        be freed more than once, causing wild memory corruptions.
	(gdb_disassembly): Look for the substring "-thread",
        instead of "-threads" in the target name, to make sure to find
        the 'multi-thread' target.  Also, make sure we do the right thing 
        with the "core" target.
