g++ gives an error compiling the source given below.
$ g++ -c x.cc
x.cc: In instantiation of `A<(&str)>':
x.cc:9: instantiated from here
x.cc:6: error: could not convert template argument `&str' to `const char*'
x.cc:6: error: could not convert template argument `&str' to `const char*'
x.cc:6: error: could not convert template argument `&str' to `const char*'
$
While i don't have a language reference handy at the moment, i don't
see anything wrong with the code. Further, gcc accepted it through
at least the beginning of January.
Oddly, the error goes away if the `const' qualifier on `str' is removed.
Environment:
System: Linux karma 2.6.1 #10 Tue Feb 10 04:31:35 EST 2004 i686 i686 i386 GNU/Linux
Architecture: i686
<machine, os, target, libraries (multiple lines)>
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --prefix=/usr/local/gcc --enable-threads=posix --enable-long-long --enable-languages=c,c++,f77
How-To-Repeat:
Compile the following:
-----------------------------------------
extern const char str[];
template <const char* P>
struct A
{
template <const char* R> void foo();
};
template class A<str>;
-----------------------------------------

Confirmed on the mainline also, I am think this patch caused it (but I do not have
anything to back it up with though except that it works on the tree-ssa which was merged
right before this patch went in):
2004-01-26 Mark Mitchell <mark@codesourcery.com>
* class.c (add_method): Just check processing_template_decl to
determine whether or not we are within a template.
* decl2.c (maybe_retrofit_in_chrg): Likewise.
* init.c (decl_constant_value): Check the type of the declaration,
not TREE_READONLY.
* name-lookup.c (maybe_push_to_top_level): Rename to ...
(push_to_top_level): ... this.
* name-lookup.h (maybe_push_to_top_level): Do not declare it.
* pt.c (push_template_decl_real): Reorder condition for speed.
(convert_template_argument): Use dependency-checking functions in
place of uses_template_parms.
(lookup_template_class): Avoid calling uses_template_parms more
than once.
(uses_template_parms): Reimplement, using dependency-checking
functions.
(instantiate_class_template): Use push_to_top_level, not
maybe_push_to_top_level.
(type_unification_real): Simplify.
(type_dependent_expression_p): Handle OFFSET_REFs and
TEMPLATE_DECLs.
(any_dependent_template_arguments_p): Handle multiple levels of
template argument.
* semantics.c (expand_or_defer_fn): Do not check
uses_template_parms for template instantiations.
* typeck.c (comptypes): Avoid calling cp_type_quals.
