This is not resolved with the fix for #99422 therefore I am re-opening.

I tried with fresh build with head being
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=0d9a70ea3881c284b7689b691d54d047b55b486d
which includes the fix for #99422

I've reproduced it.  Sorry for all the troubles.  I'll try to fix it tomorrow.

    [PR99454] LRA: Process 0..9 constraints in process_address_1

    We need to process 0..9 constraints to fetch the right op constraint in
    the function.  Also 0..9 constraints gives unknown class constraint
    class which can result in skipping address normalization for memory in asm.

    gcc/ChangeLog:

            PR target/99454
            * lra-constraints.c (process_address_1): Process 0..9 constraints
            in process_address_1.

--- Comment #6 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
The patch is not enough. It seems that there are other asms in the test which
results in LRA crash.
