Bug introduced in 8.0 and fixed in 10.1.0


While playing with Scaled, I made a syntax error which caused a crash instead of an error message ...

Do you get the same ? (I have v.10.0.2, OS X 10.9.5.)

This is how I can reproduce that :

Let's define a graphic primitive (no crash here) :

p = Disk[{0., 0.}, Scaled[{0.2, 0.2}, 2.]]

(the syntax error is the second parameter of Scaled)

To crash, try to display the corresponding graphic :

Graphics@p

It "works" also with Circle instead of Disk, and maybe with others ?

    $\begingroup$ I can reproduce this on Windows 8.1 using Mathematica 8, 9, and 10. A syntax error should not lead to a crash. Please report this to support@wolfram.com. $\endgroup$ – Sjoerd C. de Vries Jan 26 '15 at 22:13

    $\begingroup$ Well that's interesting. I'll write it up in the morning. $\endgroup$ – rcollyer Jan 26 '15 at 22:23

    $\begingroup$ @Sjoerd This does not crash Mathematica 7 so I guess I can mark this as introduced in 8.0. $\endgroup$ – Mr.Wizard Jan 26 '15 at 22:41

To ensure that this does not remain unanswered, this was fixed for 10.1. So, now it returns an FE error, as expected:

Fix is confirmed on Mac OS, Windows, and Linux.
