Bug introduced in 10.1 or earlier and persisting through 11.1

Consider the string generated by this line:

EllipticTheta::usage // FullForm

Highlight everything except the leading and trailing quotations as shown:


Attempt to copy highlighted text using ⌘+C on a Mac.

On my computer (Mac OS X 10.11, Mathematica 10.3, 10.4, 11.0), Mathematica vanishes-- the front end and the kernel is killed by the OS.

Would someone confirm this behavior? If this is a crash due to Mathematica and not my machine, I will report.


I've narrowed the pathological behavior to the part that contains \"u or \"q in the usage. I observe that any selection that contains this string as a subset will cause Mathematica to crash:

Can anyone verify this?

  • $\begingroup$ @Sascha Oh, I'm on OS X 10.11.5. Let me update to 10.11.6 and see if that fixes it. $\endgroup$

    $\begingroup$ I confirm the crash with versions 11.0.0 and 10.4.1 on Win7 x64: an attempt to copy the \"q causes immediate crash! With version 8.0.4 there is no crash. $\endgroup$ Commented Aug 28, 2016 at 19:43

I've just tried this in V11.0.0 and V10.4 on Linux (control-c to copy). In the terminal from which I launched Mathematica I see:

Mathematica has received the signal: SIGSEGV and has exited. If possible, please report this problem to [email protected] describing in as much detail as possible what you were doing when the problem occurred.
