[Bug c++/31042] New: Instantiation with const pointer to member

["wolfgang dot roehrl at gi-de dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Dear all,

I would like to post a bug report for the GNU C/C++ compiler 3.3-e500.

We use the compiler to generate code for a PowerPC processor.

Used invokation line for the GNU C++ compiler:

ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig
      -fmerge-templates -mmultiple -mno-string -mstrict-align -O3
      -fno-exceptions -fno-rtti -fno-builtin-printf
      -I<some include paths>
      -D<some #define's>
      X.CPP -oX.O


// file X.CPP

class X;

template <typename T_>
int X::** f1 () { return static_cast<T_*>(0); }

int X::** f2 () { return f1<int X::* const>(); }


The compiler gives the following error messages:

X.CPP: In function `int X::** f1() [with T_ = int X::*]':
X.CPP:6:   instantiated from here
X.CPP:4: error: invalid conversion from `int X::**' to `int X::**'


BTW, function f1 is instantiated with 'T_ = int X::* const'
and not with 'T_ = int X::*'.

Kind regards
W. Roehrl
