[Bug c++/13592] New: C++ parser regression

[rwgk at yahoo dot com]

gcc snapshot from 2003/12/30, ca. 7:40am PST
Configured with: ../gcc/configure --prefix=/usr/local_cci/gcc_cvs_2003_12_30 --
enable-languages=c,c++
Redhat Linux 8.0

gcc 3.4.0 fails to compile this piece of code:

        result[ir] = boost::lcm(
          result[ir], norm_denominator(r_(ir, ic), grid[ic]));

However, it works with this trivial modification:

        result[ir] = boost::lcm(
          result[ir], norm_denominator(this->r_(ir, ic), grid[ic]));

The original code works with many other compilers incl. earlier gcc's. Note 
that r_ is a member of the rt_mx class and *not* inherited. I will attach a 
preprocessed file that can be used to reproduce the problem and the workaround:

g++ -fPIC -ftemplate-depth-120 -w -DNDEBUG -O3 -DBOOST_PYTHON_MAX_BASES=2 -

Nathan Could you look at this bug, it looks like your patch causes it:

2003-07-18  Nathan Sidwell  <nathan@codesourcery.com>

        * cp-tree.h (finish_non_static_data_member): Add object param.
        * method.c (hack_identifier): Adjust.
        * pt.c (tsubst_copy_and_build) <COMPONENT_REF case>: Don't search
        again for a FIELD_DECL.
        * semantics.c (finish_non_static_data_member): Add object
        parameter. Always save the DECL in the COMPONENT_REF.
        * call.c (resolve_scoped_fn_name): Adjust.

Here is something that's more in our standard format: 
-------------------- 
struct S { 
    void operator()(int); 
}; 
 
struct A { 
    template <typename> void foo(); 
    S s; 
}; 
 
template <typename> void A::foo() { 
  s(0); 
} 
--------------------------

g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc 
x.cc: In member function `void A::foo()': 
x.cc:11: error: call to non-function `A::s'
