Quite possibly due to cost metrics. They are far from ideal.
Will mark test XFAIL until we can investigate and fix.

This is really not a task for SRA but for struct copy propagation (which we
do not do). See PR14295.
As this testcase was for SRA you can either XFAIL it for avr or see if the
cost metrics need adjustment.

Thanks for information
--param sra-max-structure-size=32 does indeed remove test failure and produces
optimal code.
But changing the testcase does not remove the optimization problem - unless
