The output from disassembler, which is invoked from profiler
when profiler detects zero cycles.

I don't think it happens for all instructions of certain
type, but that it happens in certain situations.

Set DEBUG to 1 in src/debug/profile.c, recompile, then do:
  echo "profiling on" > profile.ini
  hatari --trace cpu_disasm --parse profile.ini --machine falcon \
		--tos tos404.img

Check the cycle values for instructions which are reported
to have zero cycles.
