Compiler fails with segmentation fault when derefence is missing
## Summary
Compiler fails with segmentation fault when derefence is missing. The phenomenon demonstrates itself in ObjFPC mode, possibly others.
## System Information
- **Operating system:** Linux Mint 21 Cinnamon, 64 bit, Linux Kernel: 5.15.0-53-generic
- **Processor architecture:** x86-64
- **Compiler version:** 3.2.2
- **Device:** Computer
## Steps to reproduce
Compile the provided example:
## Example Project
```pascal the code
program Project1;
type
PA_Node = ^TA_Node;
TA_Node = array[0..3] of PA_Node;
var n1,n2:PA_Node;
begin
n2 := nil;
n1[3] := n2; // Panic (1002) Target OS: Linux for x86 ppcx64 can't be executed; error code -139
// n1^[3] := n2; // this of course works, I would just expect less panic for just forgotten caret
end.
```
## What is the current bug behavior?
Compiler fails with segmentation fault
## What is the expected (correct) behavior?
Compiler does not fail and produces error message
