The patch for bug 41229 seems to fix this bug too.

I couldn't duplicate this on i686-pc-linux-gnu, on a tree with a bunch of
patches approved or pending approval. If I had to guess, I'd say it's the
patch for bug 41229 that fixes it. I'm checking it in momentarily.

Forgot a step: after having copied locally system.ads edit the local copy and
change the ZCX_By_Default line as Eric described in comment #2

Alexande, you can reproduce this by just bootstraping as usual an x86_64-linux
compiler with Ada enabled then in a clean directory do:
gue...@gcc13:~/tmp41291$ gnatchop ~/pp.txt
gue...@gcc13:~/tmp41291$ cp
/home/guerby/

Thanks. Please attach it to the PR.

Here is a minimal Ada testcase:
-- file: pp.ads
with Ada.Finalization;
package Pp is
type R is new Ada.Finalization.Controlled with record
null;
end record;
procedure P (S : in String);
end Pp;

Same with g-dirope.adb, same workaround works.
g-dirope.adb: In function 'GNAT.DIRECTORY_OPERATIONS.REMOVE_DIR':
g-dirope.adb:727:4: error: expected an SSA_NAME object
g-dirope.adb:727:4: error: in statement

I see it on arm-linux too. It ICEs at -O1 and -O2 but works at -O0.
a-direct.adb: In function 'Ada.Directories.Start_Search':
a-direct.adb:1178:4: error: expected an SSA_NAME object
