Hi again,
I got this error when sage was building mathplotlib recursively as part of its
own build. It may be an error specific to my system of my version of gcc (4.9.0
20130317 (experimental)). But if anyone has insights on this error, I'd greatly
appreciate it. I haven't run into internal compiler errors before and don't
have much experience troubleshooting them.

Here's the snippet of C++ code that I plucked out of the file that triggered
the error in gcc.
---
template<class T, unsigned S=6> class pod_bvector
{
public:
enum block_scale_e
{
block_shift = S,
block_size = 1 << block_shift,
block_mask = block_size - 1
};
typedef T value_type;

Thanks,
Anton
