It's @RavenKelder being a noob, he referenced a cell outside the memory address bound,tries updating memory view.

need to handle this error in a future update.

Here is a code snippet that replicates the problem.

JumpI X
X, DEC 4096

The literal 4096 is an out-of-bounds literal, but the compiler can not detect that because a label is being used. Using a label means that we have to detect if the JumpI instruction will move the program counter outside the boundaries of the memory (and raise an error when it does happen).

[ericjiang97]

Negative Values still break.

Example Code:

Load X
Subt one
Store X
LoadI X

X, DEC 0
one, DEC 1
