           Summary: lookup in static block finds wrong type?
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal

Filing this so I don't drop root-causing this.

This isn't a complete example, but it's sufficient to recreate one.

(gdb) py print gdb.lookup_type("struct foo",
gdb.decode_line("main")[1][0].symtab.static_block()).fields()[0].name
x
(gdb) py print gdb.lookup_type("struct foo",
gdb.decode_line("baz")[1][0].symtab.static_block()).fields()[0].name
z
(gdb) start
Temporary breakpoint 1 at 0x400538: file multiple_decl1.c, line 8.
Starting program: ./multiple_decl 

Temporary breakpoint 1, main () at multiple_decl1.c:8
