[Bug] Crash when editing pattern with auto-eval enabled

[speps]

Operating System

Windows

What's the issue you encountered?

When editing a pattern and auto-eval is enabled, it crashes even though the pattern itself works with auto-eval.

How can the issue be reproduced?

Pattern:

u8 name_len @ 0x4;
char name[name_len] @ 0x5;
u32 num_samples @ (0x5 + name_len);

File: R1BS100.zip

On line 3 if you edit it by pressing Backspace with the cursor after the 5, it will crash.
