             Bug #: 53161
           Summary: index domain error, in ipa_remove_reference at
                    ipa-ref.c:84
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal

         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: dcb314@hotmail.com


I just tried to compile the package luminance-hdr-2.2.1-3
on gcc-4.8 trunk dated 20120429 on an AMD x86_64 box.

The compiler said

/home/dcb/rpmbuild/BUILD/luminance-hdr-2.2.1/src/Viewers/HdrViewer.cpp:412:1:
internal compiler error: vector VEC(ipa_ref_ptr,base) index domain error, in
ipa_remove_reference at ipa-ref.c:84
 }

Here is a reduced testcase:
extern int gg (int *__once_control);
static __typeof(gg) __gthrw_gg __attribute__ ((__weakref__("gg")));
typedef float v4sf __attribute__ ((__vector_size__ (16)));
extern v4sf  f (float __F);
void g(v4sf,v4sf);
void h(float m_MinValue) {
g(f(1), f(1.0f/2.2f));
}
--- CUT ---

Confirmed.

I also see that LTO bootstrap fails with following message

Another test case (without vectors):

$ cat test.cpp 
void gg();
static __typeof(gg) __gthrw_gg __attribute__((__weakref__("gg")));

template<typename R,typename... A>
struct data {
  template<typename Y,typename X>
  data(Y& y,R(X::*f)(A...));
};

template<typename Y,typename X,typename R,typename... A>
data<R,A...> make_data(Y& y,R(X::*f)(A...)) {
  return data<R,A...>(y,f);
}

void global(data<void>);

struct test {
  void bar() {}
  void doit() { global(make_data(*this,&test::bar)); }
};

$ g++ -std=c++11 -c test.cpp 
test.cpp:20:2: internal compiler error: vector VEC(ipa_ref_ptr,base) index
domain error, in ipa_remove_reference at ipa-ref.c:84

OK, this problem is caused by C++ FE corrupting symbol table by creating new
symbol from DECL_ASSEMBLER_NAME langhook while creating another symbol.  There
has to be better ways to produce those aliases than from here...

I am testing fix.
