This is a GCC bug which has been discussed a lot on the Pari listed, and reported in at least three places to GCC and Ubuntu. The only stated workaround at present is to build pari with -O0 instead of -O3: http://www.nabble.com/Ubuntu-9.10-and-gcc-4.4-failure-td24853751.html William William --~--~---------~--~----~------------~-------~--~----~ 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 URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
