Hi
Summary: On a mixture of sage 4.5.2, 4.5.3, and 4.6alpha3
Linux:
i7 64bit: sefgault
E8400 64bit: segfault
T4300 64bit: segfault
T3200 64bit: segfault
T2300 32bit: no segfault
OS X 10.6 (Marshall: 32 or 64 bit?): no segfault
Conjecture: It is a Linux specific 64bit problem.
Can some people on 32bit and 64bit and different CPUs (amd as well)
send in the output of
grep name /proc/cpuifo
uname -a
sage -v
sage -t devel/sage/sage/interfaces/sage0.py
dmesg|grep pari
