A method for performing a memory safety check of a program coded in an unmanaged programming language includes receiving an intermediate representation (IR) of the program and performing a static analysis pass of the IR to generate annotations including a safe pointer and an unsafe pointer. The method further includes removing, during a static analysis pass of the IR, the safe pointer from the annotations, inserting, into the IR using the annotations, a sandbox function call at the unsafe pointer to generate a modified IR, compiling the modified IR to generate an executable version of the program, executing, inside a sandbox framework, the executable version of the program, generating, during runtime and upon reaching the sandbox function call, a metadata entry and an enhanced pointer for atomicity, and comparing, during runtime and upon reaching a use of the unsafe pointer, the metadata entry with the enhanced pointer.
