           Summary: ICE/segfault on hppa2.0w-hp-hpux11.11
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: numerical dot simulation at web dot de
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: hppa2.0w-hp-hpux11.11

Hi!

Since it seems the crash appears at a rather normal place
in the code (no ET magic or so) I have no idea what might have gone wrong,
sorry.

Configured with: ../gcc/configure --prefix=/opt/FREE-SOFTWARE/gcc-20030715
--with-gnu-as --with-as=/opt/FREE-SOFTWARE/binutils-2.14/bin/as
--with-out-gnu-ld --enable-languages=c,c++
--enable-version-specific-runtime-libs --disable-multilib
Thread model: single
gcc version 3.4 20030715 (experimental)

I attach the .ii file in a minute (why is this button missing in this form?)

Looks to be target independent.
I do not have time right now to reduce it.

OK, this is as small sas I can get it:
------------------------------------
template <typename> class X;

template<class T>
void foo() {
  const unsigned int j = T().begin()->first;
  X<int> v;
  v[j].push_back(0);
}
-------------------------------------
With tonight's compiler, I get
tmp/gg> ../build-gcc/gcc-install/bin/c++ -c x.cc
x.cc: In function `void foo()':
x.cc:7: internal compiler error: Segmentation fault
Please submit a full bug report,

Note that this happens during template parsing time, not during 
instantiation. I guess the code as is is illegal (since X is not
defined at the point of use, but the original code looked definitely
legal).
