[Bug tree-optimization/21851] New: [4.1 regression] segfault with -ftree-vectorize

[bangerth at dealii dot org]

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 &#8216;Tensor<1, dim> 
AutoDerivativeFunction<dim>::gradient(const Point<dim>&, unsigned int) const 
[with int dim = 3]&#8217;: 
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 :-(
