I am running into a strange bug where taking reciprocals of a list of floating point numbers crashes the kernel with a floating point exception. This is on a Linux x86_64 system, Ubuntu 9.10, running Mathematica 220.127.116.11 Something like foo=Array[1.0&,1000]; 1/foo or foo=RandomReal/@Range; 1/foo gives me the crash Replacing floats with integers makes things work fine, also, for small enough lists (order of 10 elements) everything works. Same version of Mathematica on a 32-bit linux system or on Windows doesn't exhibit this behavior. I am rather mystified by what's going on; my hardware/OS is pretty standard, so if the bug were this obvious it would have long been known by now... But if anyone else has run into similar behavior and/or knows of some sort of a fix, please let me know. Thanks, --Leo
