Cannot help you specifically, but in the past when I have seen things
like this happening, it has often been an alignment issue. It appears
and disappears as changing sizes of text and data change the alignment
of later data items.

Check that the alignment requirements in your linker script are
correct. If you try single stepping through
cyg_hal_invoke_constructors() when it is misbehaving you should be
able to work out what is going wrong.
