Potential fix for https://github.com/SolidifyDemo/ghas-vulnerable-c-cpp-template/security/code-scanning/11

To fix the issue, we need to ensure that the function never returns a pointer to stack-allocated memory. This can be achieved by dynamically allocating memory for msg_ctxt_id in all cases, regardless of the configuration. This way, the lifetime of the memory extends beyond the function's scope, and the returned pointer remains valid.

Specifically:

1. Replace the stack-allocated array msg_ctxt_id (line 218) with a dynamically allocated buffer using malloc.
2. Ensure that the dynamically allocated memory is freed if it is not returned (e.g., when translation != msg_ctxt_id).
3. Update the code to handle memory allocation failures gracefully.
