GetTokenInformation() and FreeSid() at port/exec.c

Hi.

We found the unbalance of xxAlloc and xxFree at AddUserToDacl() in
src/port/exec.c (of current HEAD code).

psidUser is a pointer of the element of a TOKEN_USER structure
allocated by  HeapAlloc().  The FreeSid() frees a SID allocated by
AllocateAndInitializeSid().  I think that it is correct to use
HeapFree(GetProcessHeap(), 0, pTokenUser).

At present, a specific error, crash or trouble seems not to have happened.


src/port/exec.c:748     AddUserToDacl()
src/port/exec.c:841      GetUserSid()
        pTokenUser = (PTOKEN_USER) HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, dwLength);

src/port/exec.c:807      AddUserToDacl()
    FreeSid(psidUser);
