That is a fmovem.x. Can you look at the bytes after that instruction
($1044fcc-$1044fd4 in your example, they are not printed). Maybe only a bug in
the disassembler, but might also be some wrongly decoded opcode.
Here is the disasm code (some opcodes are less readable than with the
full software FPU and are displayed as dc.w) :
First, I've included the history on the 20 last instructions, then the
disasm at the first instruction after the RTS.
