I first encountered the following when revising sage-core-4.3.5-r1 to |
| 4 |
allow backporting from sage-4.4.2 to sage-4.3.5 and it appears with |
| 5 |
sage-4.4.2. If I upgrade python to 2.6.5-r99 and rebuild sage-core, |
| 6 |
sage will not start. I get: |

I could have overlooked something. I rebuilt cython with no effect. |
| 129 |
This is somewhat similar to a problem that was solved by appending |
| 130 |
"-fno-strict-aliasing" to the flags in sage-core; which is still there. |
| 131 |
None of this is present with python-2.6.4-r99. |
