Whenever I input a float number directly, e.g.
sage: 0.6
sage exits with an error message about sage-ipython instruction not allowed. Anyone has an idea about this?
OS: Linux, ArchLinux Sage Version: 4.6.1 (arch sage-mathematics binary)
My guess is that you downloaded a binary which was built for a new processor than the one that you have. If you download the Sage source code and build from scratch, everything should work fine.
Same Problem:
While running sage with gdb:
sage: a = 2.0 sage: b = 2.5
Program received signal EXC_BAD_INSTRUCTION, Illegal instruction/operand. 0x00000001016e3ed9 in case1 ()
Version: sage-5.0-OSX-64bit-10.6-x86_64-Darwin OS: Mac OS X Lion 10.7.4 (11E53) Processor : 2 x 3 GHz Quad-Core Intel Xeon
Can you post the exact CPU? Intel sold a lot of chips under the Xeon label. Is this a Core 2 Quad in disguise? As far as the supported instruction set goes, there is not much difference between a Core 2 Duo and Core 2 Quad. Please post the output of "sysctl -n machdep.cpu.brand_string"

Could you cut and paste the exact error message?
