This looks like a classic bug.
You wanted this:
.uml.setup.init : {
__uml_setup_start = .;
*(.uml.setup.init)
__uml_setup_end = .;
}
In this way you are sure __uml_setup_start has same address as start
of section.
With the original code the linker will align the .uml.setup.init section
to the alignment required by the included sections and thus
the label and the actual start address may differ.
