 A global solution is to edit your project so that when compiling with GCC on Windows, you pass this option to GCC:
 \code
--mpreferred-stack-boundary=3

+Explanation: this tells GCC that the stack is only required to be aligned to 2^2=4 bytes, so that GCC now knows that it really must take extra care to honor the 16 byte alignment of \ref FixedSizeVectorizable "fixed-size vectorizable Eigen types" when needed.
+
+Another global solution is to pass this option to gcc:
 \code
--mpreferred-stack-boundary=2
+-mstackrealign
 \endcode
-Explanation: this tells GCC that the stack should only be required to be aligned to 2^3=8 byes (in the first version) or to 2^2=4 bytes (in the second version). In both cases, this is smaller than 16 bytes, so GCC now knows that it really must take extra care to honor the 16 byte alignment of \ref FixedSizeVectorizable "fixed-size vectorizable Eigen types". However, you must make sure that you understand fully what this does, before applying this change to your project. Read the GCC manual page. A too low value of \c -mpreferred-stack-boundary can result in poor performance: for example, on various CPUs, double-precision numbers work much faster when aligned to 8 bytes boundary, which is guaranteed by \c -mpreferred-stack-boundary=3 but not by \c -mpreferred-stack-boundary=2, so passing \c -mpreferred-stack-boundary=2 can result in poor performance! On the other hand, notice that the higher the value of \c -mpreferred-stack-boundary, the bigger the code size.
+which has the same effect than adding the \c force_align_arg_pointer attribute to all functions.
+
+These global solutions are easy to use, but note that they may slowdown your program because they lead to extra prologue/epilogue instructions for every function.

+\section newvector The new and improved workaround for std::vector
+
+Well, except that in Eigen 2.0 the <Eigen/StdVector> header causes some compatibility issues as it reimplements the std::vector<T> container in a not-fully-compatible way. If you want to avoid these issues, starting in Eigen 2.0.6 a new implementation is available, which will become default in the next major version of Eigen. You can enable it by defining EIGEN_USE_NEW_STDVECTOR:
+
+\code
+#define EIGEN_USE_NEW_STDVECTOR
+#include<Eigen/StdVector>
+\endcode
+
+This new implementation <a href="http://eigen.tuxfamily.org/dox-devel/StlContainers.html#vector">is documented here</a>. In particular, note that if you use it, you must specify Eigen::aligned_allocator<T> as the allocator type, otherwise it doesn't make any difference from the standard std::vector. This new std::vector implementation \b only overrides the standard one if used with this allocator, which guarantees that it doesn't break existing non-Eigen code.
+
+
 <span class="note">\b Explanation: The resize() method of std::vector takes a value_type argument (defaulting to value_type()). So with std::vector<Eigen::Vector4f>, some Eigen::Vector4f objects will be passed by value, which discards any alignment modifiers, so a Eigen::Vector4f can be created at an unaligned location. In order to avoid that, the only solution we saw was to specialize std::vector to make it work on a slight modification of, here, Eigen::Vector4f, that is able to deal properly with this situation.

+
+First of all, you need to find out where in your own code this assertion was triggered from. At first glance, the error message doesn't look helpful, as it refers to a file inside Eigen! However, since your program crashed, if you can reproduce the crash, you can get a backtrace using any debugger. For example, if you're using GCC, you can use the GDB debugger as follows:
+\code
+$ gdb ./my_program          # Start GDB on your program
+> run                       # Start running your program

+> bt                        # Obtain the backtrace
