This happens when you use MEM for addresses that aren’t guaranteed to be near the base pointer. It isn’t specific to debug builds, it will just silently access the wrong address in non-debug builds causing incorrect results and memory corruption. It needs to be changed to either make sure stuff it wants to access with MEM lives somewhere it can reach it, or change it to use UML_LOAD/UML_STORE for random heap addresses. |

But anyway, without knowing the actual code it’s trying to recompile when this happens it’s going to be like searching for a needle in a haystack. |
