956 .4byte $LFB4-.
Are you sure that this is not an assembler problem?

BTW, this has little to do with debugging; it's unwind information,
which is runtime.

The feature was removed from the assembler, because it is not ABI
compliant. This is fixed in GCC 3.4 and later. You can just delete
the definition in config/mips/linux.h that causes this.
ASM_PREFERRED_EH_DATA_FORMAT or something similar, I don't remember the
spelling.

hmm, sorry about that, was (as usual) confused by the
bug tracking tool ... didn't even notice that I selected
debug (I probably did, or didn't I?)

tested with binutils 2.15.91.0.1, at least those give
the very same message ...
/root/tmp/ccHAa3KN.s: Assembler messages:
/root/tmp/ccHAa3KN.s:955: Error: operation combines symbols in different segments
