[lmi] wx-2.9.2: "bug in wxDatePickerCtrl: m_date not in sync"

[Greg Chicares]

I've built this tarball:
  ftp://ftp.wxwidgets.org/pub/Daily_HEAD/files/wx-all-2010-11-06.tar.gz
and compiled the 'skeleton' trunk (using HEAD, modified a few minutes ago):
  http://svn.savannah.nongnu.org/viewvc/skeleton/?root=lmi
Now when I run
  /opt/lmi/skeleton/bin[0]$./skeleton.exe --unit_test
the diagnostic messagebox copied below appears; I select "No", and the
program crashes. It appears that the failing unit test attempted to set the
value in a wxDatePickerCtrl to one day past its upper limit; the applicable
code in skeleton/mvc_test.cpp would be:

    // Born one day after as-of date, which is forbidden. There is a
    // subtle difference between datepicker and spin controls, at
    // least for msw: an attempt to set a value outside the permitted
    // range is simply ignored for a datepicker (it keeps its old
    // value), but is respected to the extent possible for a spin
    // control (its value is set to whichever limit is closer to the
    // requested new value).

    LMI_FOCUS(birthdate);
    birthdate.SetValue(ConvertDateToWx(calendar_date(ymd_t(19560114))));
    LMI_YIELD(2, "Try to set birthdate to 19560114, one day past the upper 
limit.");

I'm not absolutely certain that lmi would ever attempt such an operation, but
I can't easily rule it out either. With wx-2.9.0, all these unit tests passed.
Is this a wx anomaly that should be fixed?

Do you want to stop the program?
