Repros at e830f10. The jit is crashing during LSRA while jitting testout1.Func_0_2_3_4().

Seems like interval is invalid here:

Will see if this repros using an altjit.

Yes, repros with

@kunalspathak do you want me to keep digging in, or do you want to take this one over?

kunalspathak · 2021-03-30T19:18:42Z

Thanks @AndyAyersMS for getting minimal repro. I can look into it.

kunalspathak · 2021-04-07T00:22:11Z

I was able to repro the issue on e830f10 but it doesn't repro on main. I will investigate further.
