Description Prashant Cholachagudda 2014-12-18 04:31:36 UTC
We get asserts when we try to compile our project to run on hardware
(works on the simulator), and it turns out just trying to build a simple F#
project shows the same error:
Mono Ahead of Time compiler - compiling assembly
unknown opcode jmp in mono_arch_output_basic_block()
* Assertion: should not be reached at
