Hi,

The following small program gives ICE when compiled like this:

g++ -Wall -fopenmp -O2 -I$POLDEST/ext/include -E -o./test_pp.cc ./test.cc
g++ -Wall -fopenmp -O2 -L$POLDEST/ext/lib -o./test ./test_pp.cc -lblitz -lgomp
./test.cc: In function ‘int main()’:
./test.cc:3: internal compiler error: Segmentation fault

When removing the 'try-catch'-part it works fine.

----
#include <blitz/array.h>

int main()
{
  try
  {
    blitz::Array<float,1> transOrig( 10);
    blitz::Array<float,1> trans( 10);
    blitz::Range myRange( 0, 9);

#pragma omp parallel for
    for( int i = 0; i < 2; ++i)
    {
      trans += transOrig( myRange);
    }
  }
  catch( std::exception)
  {}
}

And my specs: ~> gcc -v
