Hi all,
Following my message on the "gdb" list
(http://sources.redhat.com/ml/gdb/2006-04/msg00327.html),
here is the patch I propose.
Christophe.

* gdb.cp/m-static.h (class gnu_obj_4): Add dummy member.
* gdb.cp/m-static.cc (main): Write to test4.dummy, so that test4
is allocated by the compiler.
* gdb.mi/var-cmd.c: (do_special_tests): Write to u, anonu, s,
anons, e, anone to force their allocation by the compiler.
