AOC compile error

I compiled my OpenCL code with AOC 17.1.2 Build 304 and got cryptic error messages shown below. Can anyone please let me know what causes such crash?

These types of LLVM errors generally happen when the kernel is FPGA-unfriendly, or too complex for the compiler to handle. There is no fixed cause for them, nor is there a fixed solution. You can generally bypass them by refactoring your kernel and making it more FPGA-friendly. Other than that, you can also directly open a ticket with Altera and report the issue since this is basically a compiler bug, and only they can fix it.
