I've been dealing with mangling issues recently.

Fixed by Jason's patch

2009-03-17  Jason Merrill  <jason@redhat.com>

        * decl.c (grokfndecl): Set DECL_CONTEXT on parms.
        (duplicate_decls): Adjust DECL_CONTEXT of newdecl's parms.
        * pt.c (check_explicit_specialization): Likewise.
        (tsubst_copy) [PARM_DECL]: Return a dummy parm if we don't have a
        local specialization.
        * tree.c (cp_tree_equal) [PARM_DECL]: Check type and index, not name.
        * decl2.c (parm_index): New fn.
        * semantics.c (finish_decltype_type): Don't use describable_type.
        * mangle.c (write_expression): Likewise.  Mangle ALIGNOF_EXPR.
        Give a sorry for unsupported codes rather than crash.  Mangle
        conversions with other than 1 operand.  New mangling for PARM_DECL.
        * operators.def (ALIGNOF_EXPR): Mangle as "az".

It shouldn't be closed without a testcase.

Even though the testcase in comment #2 compiles, it fails to link:

tmp/ccsV5xgT.o: In function `main':^M
pr4926-1.C:(.text+0x5): undefined reference to `X<sizeof
((P(((F)())())).array)>::Type foo<F>()'^M

I'm sorry, where is the definition of foo? Of course it doesn't link.

------- Comment #12 from hjl dot tools at gmail dot com  2009-04-01 18:13 -------
The testcase in the first attachment still failed to compile as of
revision 145378:

[hjl@gnu-6 gcc]$ ./xgcc -B./ -S
/export/gnu/src/gcc-work/gcc/gcc/testsuite/g++.dg/template/foo.ii
/export/gnu/src/gcc-work/gcc/gcc/testsuite/g++.dg/template/foo.ii: In function
‘int main()’:
/export/gnu/src/gcc-work/gcc/gcc/testsuite/g++.dg/template/foo.ii:45: sorry,
unimplemented: mangling template_id_expr
/export/gnu/src/gcc-work/gcc/gcc/testsuite/g++.dg/template/foo.ii:45: sorry,

/export/gnu/src/gcc-work/gcc/gcc/testsuite/g++.dg/template/foo.ii:45: sorry,

Is this expected?

That is in fact still unimplemented, and a good reason not to close the PR.

Actually, we have PR 38712 specifically about the template-id case, so let's go
ahead and close this PR.
