Expected Behavior

The strings should be placed in read-only memory so trying to modify them will cause a crash

Current Behavior

They dont seem to be put in read-only memory so they can be modified and break other identical string literals in the program

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

import "core:fmt"

main :: proc() {
