           Summary: ICE with -pg
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rguenth at tat dot physik dot uni-tuebingen dot de

The POOMA based testcase (sorry for it being so large) at

http://www.tat.physik.uni-tuebingen.de/~rguenth/gcc/Bench.ii.gz

compiled with

g++-3.4 -c Bench.ii -ftemplate-depth-60 -fno-exceptions -O2 -march=athlon
-funroll-loops -ftime-report -pg -g

yields the following ICE:

/home/rguenth/src/pooma-bib/r2/src/Array/ArrayOperators.h: In function `typename
MakeReturn<BinaryNode<OpEQ, typename CreateLeaf<Array<D1, T1, E1> >::Leaf_t,
typename CreateLeaf<T2>::Leaf_t> >::Expression_t operator==(const Array<D1, T1,
E1>&, const T2&) [with int D1 = 1, T1 = double, E1 = MultiPatchView<GridTag,
Brick, 1>, T2 = double]':

but not, when omitting -pg. It does even ICE with just -O0 -pg.
