With attached code, I get a segmentation fault:
spec/src> c++ -c -O -march=pentium4m -ftree-vectorize
auto_derivative_function.ii
auto_derivative_function.ii:6859: warning: ‘__malloc__’ attribute ignored
auto_derivative_function.ii: In member function ‘Tensor<1, dim>
AutoDerivativeFunction<dim>::gradient(const Point<dim>&, unsigned int) const
[with int dim = 3]’:
auto_derivative_function.ii:32007: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Unfortunately, I have no time right now to reduce this code further :-(
