| When testing the XOR generator with dieharder(1), the program segfaults:

| zsh: segmentation fault dieharder -g 207 -a
I can confirm that.
There has not been a whole lot of upstream development in quite some time so
not sure how likely it is that we will see a fix.

| According to the dieharder(1) manpage, the XOR `supergenerator' uses the
| `AES_OFB', `Threefish_OFB', and `kiss' generators, XOR-ing them together:
|
| `... for the hypercautious the XOR generator with AES, threefish, kiss,
all
| loaded at once and xor'd together.'
|
| Running the tests separately does not segfault:
|
| % dieharder -g 205 -a
| (...snip...)
| % dieharder -g 206 -a
| (...snip...)
| % dieharder -g 208 -a
| (...snip...)
