[Bug c++/29182] New: ICE in make_decl_rtl, at varasm.c:890

[michael dot haubenwallner at salomon dot at]

While building mico-2.3.11 on hppa2.0w-hp-hpux11.11, got this error:

$ c++  -I../include  -O2  -Wall  -g -pthread -D_REENTRANT   -DPIC -fPIC  -c
valuetype_impl.cc -o valuetype_impl.pic.o
../include/mico/valuetype_impl.h: In member function 'void
CORBA::DataOutputStream_impl::_ZTv0_n68_N5CORBA21DataOutputStream_impl16write_longdoubleEe(CORBA::LongDouble)':
../include/mico/valuetype_impl.h:44: warning: 'value___2332' is used
uninitialized in this function
valuetype_impl.cc:638: internal compiler error: in make_decl_rtl, at
varasm.c:890
Please subm<snip>

It is independent of at least those compilerflags: -g/-O*/-pthread/-fPIC

Strange: If I remove all the #line directions from preprocessor output, the
error is different:

$ c++ -c valuetype_impl.ii -o valuetype_impl.o                          
valuetype_impl.ii:32: error: redeclaration of C++ built-in type 'wchar_t'
valuetype_impl.ii: In static member function 'static wchar_t
std::numeric_limits<wchar_t>::min()':
valuetype_impl.ii:6640: warning: left shift count >= width of type
valuetype_impl.ii: In static member function 'static wchar_t
std::numeric_limits<wchar_t>::max()':
valuetype_impl.ii:6642: warning: left shift count >= width of type
valuetype_impl.ii:49485: confused by earlier errors, bailing out

Attached is the preprocessor output, from original command with '-save-temps'.
I have it bzip2'ed, as I'm unable to reduce it to a small testcase.

Have built gcc with one patch, found here:

[Bug c++/29182] ICE when using long double with virtual inheritance and virtual methods

[michael dot haubenwallner at salomon dot at]

------- Comment #2 from michael dot haubenwallner at salomon dot at  2006-09-22 14:46 -------
was playing around somewhat after posting and indeed found the small testcase:

$ cat aa.cc

class A {
        virtual void f(long double);
};

class B : virtual public A
{
        void f(long double);
};

void B::f(long double x)
{
}

$ c++ -c aa.cc        
aa.cc: In member function 'void B::_ZTv0_n12_N1B1fEe(long double)':
aa.cc:7: internal compiler error: in make_decl_rtl, at varasm.c:890
Please submit a full bug report,
with preprocessed source if appropriate.
