Summary: StaticBoxSizer causes segfault on exit

Initial Comment:
If a StaticBoxSizer is created, it seems to cause a segfault on exit. Adding just this line to MinimalFrame#initialize in the minimal sample shows the error:

    sizer = Wx::StaticBoxSizer.new(  Wx::HORIZONTAL, self, 'foo' )

On OS X 10.3, working on the wxw28 branch, the backtrace is:

Program received signal EXC_BAD_INSTRUCTION, Illegal instruction/operand.
0x00836264 in ?? ()
(gdb) whe

(gdb)

The relevant method from sizer.cpp is:

wxStaticBoxSizer::~wxStaticBoxSizer()
{
    delete m_staticBox;
}
