  • Ticket #4181 – Description

    initial v1  
    11On both my Mac OS X 10.4 / Xcode 25 boxes, one Intel and one PPC, the following Sage code runs through fine (hit return twice):
    2 
     2{{{
    33sage: for p in prime_range(32768, 100000):  EllipticCurve(GF(p),[0,1,1,10,13])
    4 
     4}}}
    55Please note that the length of the interval is almost 70000, so quite some primes are involved.
    66But if the startpoint of the range is lower the 32768, then Sage crashes, e.g. for:
    7 
     7{{{
    88sage: for p in prime_range(31300, 32600):  EllipticCurve(GF(p),[0,1,1,10,13])
    9 
     9}}}
    1010(note that the length of the interval is only 1300) one gets the following message with sage crashed:
    11 
    12 
     11{{{

    1817
    1918The problem/bug can't be due to low physical RAM, or due to not enough virtual RAM for processes, since then the first line of code would have to crash, too. Which is not the case.
