I've redone and I might have something. First run had the compiler-build 
with default options, second had it with OPT=-O-, third also ran the 
tests with -O- in case that was significant. That resulted in three 
directories in tests/output:

sparc-linux-optimiser-on
sparc-linux-optimiser-off
sparc-linux-optimiser-off-during-tests

Running diff:

# diff ./sparc-linux-optimiser-on/faillist
