             Bug #: 52581
           Summary: ICE with gcc-4.7 for H8300-elf target.
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ajinkya.dhobale@kpitcummins.com


Hello,

I am newbie to GNU GCC.
I am working on H8300 architecture and version detail for my toolchain sources
are as follows,

gcc = 4.7.0-RC-20120302
binutils = 2.22
newlib  = 1.20.0
mpfr = 3.0.0
mpc = 0.8.2
gmp = 5.0.1
native gcc = 4.3.2
OS = Fedora 10

All sources are used without any modificaion except gcc source.
Modification done in gcc source is as follows,
============================================================================
In "libstdc++-v3/include/bits/random.tcc"

const size_t __m = std::max(__s + 1, __n);

replaced with,

const size_t __m = std::max((size_t)(__s + 1), __n);


In "libstdc++-v3/include/std/bitset"

const size_t __nbits = std::min(_Nb, std::min(__n, __len - __pos));

replaced with

const size_t __nbits = std::min(_Nb, std::min(__n, (size_t)(__len - __pos)));
============================================================================

After successful built of binutils, gcc and newlib, 
I am facing problem while building toolchain during final gcc make.
GCC configure command: "make > makelast.out 2>&1".

Error message is as follows,
============================================================================

All the help you can provide will be very appreciated.
Thank you very much.

If these are necessary for portability then please open a separate bugzilla
report, with component=libstdc++, thanks.

an internal compiler error indicates a component=c++ bug, not a
component=libstdc++ bug

Please attach a preprocessed testcase to the PR.  In your case, you should be
able to generate this by trying to build libstdc++ with CXXFLAGS=-save-temps
and then attaching bitmap_allocator.ii.
