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
\"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?
