Re: [sage-devel] Re: libpari segfault related to 64bit?
Setting SAGE_CHECK=yes just means that after building the pari
library, the self-test routines are also run. It does not affect Sage
after the new spkg is installed.

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 regards, Jan -- .~. /V\ Jan Groenewald /( )\www.aims.ac.za ^^-^^ -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
