Hi Marco,

The new test FAILs when tested on x86_64 with -m32.  I.e.,:

  make check-gdb TESTS=gdb.python/py-format-string.exp RUNTESTFLAGS='--target_board unix/-m32'

The failures I'm seeing:

  python print (gdb.parse_and_eval ('a_base_ref').format_string (deref_refs=True))
  @0xffffbb98: {_vptr.Base = 0x80487a4 <vtable for Deriv+8>, a = 42, static a_static_member = 2019}
  (gdb) FAIL: gdb.python/py-format-string.exp: format_string: lang_cpp: a_base_ref with option deref_refs: deref_refs=true
  ...
  python print (gdb.parse_and_eval ('a_base_ref').format_string (deref_refs=True, static_members=False))
  @0xffffbb98: {_vptr.Base = 0x80487a4 <vtable for Deriv+8>, a = 42}
  (gdb) FAIL: gdb.python/py-format-string.exp: format_string: lang_cpp: a_base_ref with option deref_refs=True, static_members=False

Here is the BuildBot run:

  https://gdb-build.sergiodj.net/builders/Fedora-x86_64-m32/builds/12191

And the logs:

Let me know if you need help investigating these.

Thanks,
