[Bug c++/27650] New: internal compiler error while compiling Gecode

[Harmon dot Nine at gmail dot com]

On cygwin system, used gcc 3.4.4 to compile gcc 4.1.0.  Installed gcc 4.1.0 in
/usr/local.

While compiling Gecode (with "make"), from gecode-1.1.0.tar.gz, encountered the
following error:

search/reco-stack.cc:85: internal compiler error: in maybe_emit_vtables, at
cp/decl2.c:1548

exact command sequence in top directory of gecode source tree:
$ ./configure CC="/usr/local/bin/gcc.exe" CXX="/usr/local/bin/g++.exe"
(lots of output)
$ make
(some output)
ERROR MESSAGE AS ABOVE

[dannysmith at users dot sourceforge dot net]

------- Comment #5 from dannysmith at users dot sourceforge dot net  2006-05-22 21:19 -------
This is a dllimport bug.  Dllimports do not have constant address.  Hence class
vtable cannot contain a method with dllimport attribute
I am working on  a patch.
Here is reduced testcase:


// dllimport_virtual.C
struct base
{
  virtual void key_method();
  __attribute__((dllimport)) virtual ~base(); // Does not have a const address
};

// Definition of key_method forces emmission of vtable
void base::key_method() {};

Bugfix worked for me.  Compilation definitely got farther.  However, there's
another bug.  Pls. see bug 26622.

Gecode may be a good compiler test package; it seems to use some advanced C++
features.

As mentioned in that PR, the problem there is unrelated to your code.
The rtl pattern which is being complained about:
(insn 491 490 492 18 ././kernel/core.icc:1448 (set (reg:SI 223)
        (const:SI (plus:SI (mem:SI (symbol_ref:SI ("#i._ZN6Gecode5Space3vtdE")
<var_decl 0x19664f10 vtd>) [0 S4 A8])
                (const_int 1024 [0x400])))) -1 (nil)
    (nil))


Why is this wrapping itself inside a const when it cannot be a const as it is
loading from memory.
