The file compiles without problems at -O0. With this change and the
workaround from PR ada/18217, I was able to finish a C and Ada bootstrap.

Hmm, I did get a different ICE before on this file when I was trying to confirm PR 18237 so it might be
the same bug, I will let my build go and see what happens.

Confirmed.
static struct gnat__strings__string_list_access C.572 = {.P_ARRAY=(struct
gnat__strings__string_access[(long int) <PLACEHOLDER_EXPR struct
gnat__strings__string_list_access>.P_BOUNDS->LB0 .. (long int) <PLACEHOLDER_EXPR struct
gnat__strings__string_list_access>.P_BOUNDS->UB0] *) C.2650_12486, .P_BOUNDS=&C.2650};
Note C.2650_12486, I think this is an SRA bug as we don't have it before SRA, but after wards we do. I
think it comes from not copying the tree before setting gimplifying the tree.

Oh, I think I have a fix, testing it right now, basically we need to unshare the expression before
gimplifying the DECL's initialize.

I had forgotten about that change; this seems to be fixed on mainline by
now.

Yes that is fixed, with my two just applied patches and the one which was posted above,
