Segfault on OS X 10.11 El Capitan + GeForce GT 750M about scallion HOT 6 CLOSED

enabling the "non optimized" kernel worked for me. Not sure what needs to be done to take advantage of the optimized kernel.

Same issue with OS X El Capitan 10.11.1 + Mono 4.2.1.102 w/ latest b186848. Works fine with -d 0 (i7-4850HQ) or with -d 1 (Iris Pro 5200) but selecting -d 2 for the GeForce 750M segfalts.

Looks like an issue with the Nvidia Card or with MacOS 10.11.1. On AMD Radeon R9 M370X with the current on MacOS 10.11.2 is everything fine.
