The kernel dies when using variables with different registers. #44

Open devcrocod opened 4 years ago

devcrocod commented 4 years ago

The kernel dies when the following code is executed:

fun stack(vararg tup: Int): Int = tup.sum()
val X = 1
val x = stack(1, X)

In this case, the code is executed if you use other names for X or x.

The error itself is as follows:

I got this error using latest kernel versions - 0.7.40.145 and 0.7.41.190. There was no such error on the old version. As far as I remember it was version 0.7.12.
