The causing instructions is 674696a -- depending on the endianness, it's
either:
6a697406 ldl t1,29702(s3)
which requires at least MIPS III or:
0674696a 0x674696a
which is completely invalid.
There are a few ways to track the reason down:
1. Figure out which binary or shared library 0x2abb034 belongs to and
disassemble the surrounding code.
2. Enable core dumps, run the failing program and do a post-mortem
analysis of the resulting dump with gdb.
3. Run the failing program under gdb and see where SIGILL happens.
4. Perhaps others.

You really want "-S" instead of "-d" (there's usually no point to
disassemble data) and add "-m mips:isa64" or a similar, suitably high ISA
selector (depending on binutils version), so that you get a disassembly of
all instructions as opposed to those defined by the MIPS I ISA only.
