Current libcc1 uses just: make_node (RECORD_TYPE)
which crashes on:
if (TREE_CODE (TYPE_NAME (type)) == IDENTIFIER_NODE)
as TYPE_NAME (type) == NULL .

Attempted GCC fix.
With this GCC fix and the GDB reproducer it looks as fixed:
gdb command line:1:1: error: invalid use of incomplete typedef ‘({anonymous})’
But after running gdb.compile/compile.exp one gets another crash so this GCC
fix is probably not right.

BTW the GDB patch is wrong, it is used only as a reproducer of the GCC crash.

I think this was fixed by
commit 8db29d88f3e8d5fc43b25d9e0049c25f6bfb74d1
Author: Alexandre Oliva <aoliva@redhat.com>
Date: Tue Jan 31 01:02:03 2017 +0000
Introduce C++ support in libcc1
in particular the code now does
tree node = make_node (code);
tree type_decl = build_decl (input_location, TYPE_DECL, NULL_TREE, node);
TYPE_NAME (node) = type_decl;

Tried it again today and it seems fine:
(gdb) compile code sv.p = &sv;printf("%p %p\n",&sv,sv.p);
gdb command line:1:12: warning: incompatible implicit declaration of built-in
function ‘printf’ [-Wbuiltin-declaration-mismatch]
gdb command line:1:1: note: include ‘<stdio.h>’ or provide a declaration of
‘printf’
0x402010 0x402010
Going to close the bug this time.
