New description:
This ticket used to be about prime_pi() segfaulting, but due to a mixup of
versions used and switching to a new algorithm in 3.4.2.a0 the cause is
the following:
{{{
mabsh...@sage:/scratch/mabshoff/sage-3.4.2.final$ ./sage
----------------------------------------------------------------------
| Sage Version 3.4.2.rc0, Release Date: 2009-04-30 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: len(prime_range(2^50))
/scratch/mabshoff/sage-3.4.2.final/local/bin/sage-sage: line 198: 13833
Segmentation fault sage-ipython "$@" -i
}}}
Alex's comments are about the old ticket. This problem with wrong results
has been moved to #5963.
Cheers,
Michael
