error: cast from int16_t to int32_t loses precision

retdec produces code like

```c
int16_t* some_int = NULL;

(int32_t) some_int;
```

which fails to compile

```
main.cpp: error: cast from ‘int16_t*’ {aka ‘short int*’} to ‘int32_t’ {aka ‘int’} loses precision [-fpermissive]
```

The issue names no source file or test. Start by reproducing the shown generated C++ snippet and trace the RetDec code-generation path that emits the pointer-to-int cast. Done means the affected output compiles without the reported precision-loss error on the relevant target.
