No, it doesn't segfault. > Because when I build FEMhub, which is much smaller than Sage, my > cygwin on my windows 7 can't handle it and segfaults.

The Cygwin webpage says "Note that the official support for Windows 95, Windows 98, and Windows Me will be discontinued with the next major version (1.7) of Cygwin, which is in beta testing right now. Note that Windows 7 and later will only be supported starting with the 1.7 version of Cygwin." So it sounds like support for windows 7 is "beta". -- 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 URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
