Bug introduced in 10.0 and fixed in 11.0

Can somebody help me understand why the following code snippet cause the Mathematica kernel to crash (without producing any further error messages)?

Block[
 {
  $MinPrecision = 100,
  x = 1.`100 + 10^-55
  },
 HypergeometricU[1 - I - x, -1.`100 - I, - I]
 ]

I have tested on versions 8, 10.2 and 10.4 (all under Windows) and all produce a crash.

Update: Further testing reveals that it also crashes under Linux in version 10.2, but not in version 9.0 interestingly.

  • $\begingroup$ Crashes on "10.3.1 for Microsoft Windows (64-bit) (December 9, 2015)" but works fine on "11.0.0 for Microsoft Windows (64-bit) (July 28, 2016)". $\endgroup$

  • $\begingroup$ Good to hear that it appears to not crash in 11. (That may be a reason to update my version). Just to be curious, does evaluating the expression in 11 produce any error messages? $\endgroup$
