Actually I was wrong. It was a way heap allocation works that confused me,
actually table are allocated on heap and are plain pointers, not handles of any
kind. I was able to figure out basic structure of it:

---
struct stringtable {
    void *data; /* pointer to actual string data */
    DWORD offset; /* offset where data actually starts */
    DWORD allocated; /* allocated byte size 'data' points to */
    DWORD unk[3];
    LCID lcid; /* thread LCID, it's store on allocation and probably used to
compare */
}
---

Returned string ids are offsets from 'data' pointer to actual string data. I
didn't try to see what happens with extra data.

So unless there's an indication that installer uses internal structure for
something it looks like a general heap corruption.
