```c++
module;
#include <cstdlib>
export module Types:Allocator;
export
template <typename ElementType>
class TAllocator {
public:
static ElementType* Allocate(unsigned int sz) {
return malloc(sz);
}
};
```
```c++
export module Types;
export impot :Allocator;
```
```
error: use of undeclared identifier 'malloc'; did you mean '_alloca'?
return malloc(sz);
^~~~~~
_alloca
```
If i move this implementation to main module, and not it's partition, code compiles.
If i use this code with other simmiliar modules, and they cross at some point, error becomes bigger.
