Indeed it is a linker script problem.  The linker script specifies the
vma of .bss, placing .bss immediately after .data, but the linker
places the orphan .gcc_except_table after .data.  I don't think there
is any good reason to specify the vma on any of the sections in the
linker script (and even more peculiarly, lma on .data).  Also, I
wonder whether __data_load_end should include orphan sections like
.gcc_except_table.
