fixed in 10.0.2

RawArray seems to crash the kernel on my machine

RawArray["Byte", {}]

Is this a bug? Any insights why this happens?

My system:

version 10.01 on Mac OS X 10.0

enter image description here


I heard back from the technical support that "a correction is already being worked on for a future version".

  • $\begingroup$ Well, it is an undocumented thing, not meant for public consumption ... do you have any reason to believe that it should work? $\endgroup$

    $\begingroup$ @Szabolcs It has been used in the documentation example of Raster3D (under Neat Examples). I was playing with the parameters in the example and it crashed the kernel. $\endgroup$ Oct 25, 2014 at 6:44
  • $\begingroup$ I can reproduce the crash on Win7 64 Pro SP1, Mma . I think that crashing the kernel is not an acceptable behaviour, irrespective if its an undocumented function or not. Anybody available to test on Linux? $\endgroup$

    $\begingroup$ @rhermans If you were implementing hybrid Mathematica/C libraries, I think you woulnd't say that. Mathematica happens to be a language where it's not easy to hide the internal wiring. "Undocumented" often really means that it's a helper function for the developer, not meant for the end user. Implementing checks to make sure all arguments passed to a function are correct and reporting errors if they aren't is a lot of work, not to mention it also hurts performance. It just makes no sense to include these checks for a function not meant for public consumption. $\endgroup$

    $\begingroup$ Of course if RawArray is used somewhere in the documentation that makes things a bit different, but we knew Mathematica was messing ... BTW it also crashes in v9 but not in v8. $\endgroup$

This has been fixed in version 10.0.2. On windows 7:

(*10.0 for Microsoft Windows (64-bit) (December 4, 2014)*)

RawArray["Byte", {}]

Mathematica graphics

No crash. Just the above error message.
