The following small program gives an segmentation fault when compiled like
this:
extgccsrc> g++ -Wall -fopenmp -O2 -I$POLDEST/ext/include -L$POLDEST/ext/lib
-otest test.cc -lblitz -lgomp -lm
test2.cc: In function Âint main()Â:
test2.cc:7: internal compiler error: Segmentation fault
When removing the 'try-catch'-part it works fine.
----
#include <iostream>
#include <blitz/array.h>
int main()
{
try
{
blitz::Array<blitz::TinyVector<float,3>,3> gradients(100,1,1);
gradients = blitz::TinyVector<float,3>(0,0,0);
#pragma omp parallel for
for( int lev = 0; lev < 100; ++lev)
{
blitz::TinyVector<int,3> pos( lev,1,1);
blitz::TinyVector<float,3> normGradForward =
gradients(pos);
blitz::TinyVector<float,3> normGradLeft =
blitz::cross( normGradForward, normGradForward);
}
}
catch( std::exception& err)
{
std::cerr << err.what() << std::endl
<< "try -h for help\n";
}
return 0;
}

Here my specs:
extgccsrc> gcc -v
