-On a 32-bit system, a pointer declared with **`__ptr64`** is truncated to a 32-bit pointer. On a 64-bit system, a pointer declared with **`__ptr32`** is coerced to a 64-bit pointer.
+On a 32-bit system, a pointer declared with **`__ptr64`** is treated as a 32-bit pointer and truncates the upper 32 bits of any 64-bit address assigned to it. On a 64-bit system, a pointer declared with **`__ptr32`** is treated as a 32-bit pointer and truncates the upper 32 bits of any 64-bit address assigned to it. This truncation can lead to an invalid pointer if the 64-bit address is above 4GB.

 ## Example
 
 The following example shows how to declare and allocate pointers with the **`__ptr32`** and **`__ptr64`** keywords.
 
+This code works on x86 but might crash on x64.
+
+- It works when compiled for 32-bit because **`__ptr64`** pointers are treated as 32-bit pointers on x86. On x86 (32-bit), `malloc` returns a 32-bit address which fits in `p64`.
+- It might crash when compiled for 64-bit because on x64, `malloc` returns a 64-bit pointer which is truncated to 32 bits by this line: `p32 = (int* __ptr32)malloc(4);`. Truncating a 64-bit address to a 32-bit address could result in an invalid pointer if the allocation happened above 4GB. In that case, `*p32 = 32` could attempt to access a truncated address that isn't part of your process's address space, causing an access violation. Even if it works once, it could fail later if the memory allocator returns a higher address.
