[Bug c++/36107] New: weak constructor product unvalid asm

["william dot fink at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When using __attribute__((weak)) on a constructor, the produced assembly file
contains an extra *INTERNAL* on the constructor declaration line.

- Here is my test code:

class Test {
  public:
  Test() __attribute__((weak));
};

int test() {
  Test test;
}

- The compilation output:
$ g++ test.cc 
/tmp/cchKRpYD.s: Assembler messages:
/tmp/cchKRpYD.s:22: Error: junk at end of line, first unrecognized character is
`*'

- The corresponding asm line 22:
        .weak   _ZN4TestC1Ev *INTERNAL*

I have tried this with and it does not work for:
- gcc (GCC) 4.3.0 (compiled from sources)
- gcc-4.2 (GCC) 4.2.1 (Ubuntu 4.2.1-5ubuntu4)
- gcc-4.1 (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

It works without problems with:
- gcc-3.4 (GCC) 3.4.6 (Ubuntu 3.4.6-6ubuntu2)

If I manually remove the '*INTERNAL*' from the asm file, it compiles correctly.

I found a similar old bug (6418) from the GCC3.04 version
