Stepping into the code posted, the cch was 165 (and in other experiments when
I increased the initialized size that I was requesting for the buffer, up to
195) , in all cases it was much less than >= MAXDWORD / sizeof(WCHAR), yet
stepping through the code in a debugger, it steps into the code posted which
returns the 'Not enough memory to allocate string of size: 165' message, and
does not make any sense. The pointer that is passed into ppwz was
initialized to NULL prior to calling StrAllocSecure().
I can see that when other StrXxx functions like StrAllocConcatSecure, also
call this code block they iterate through allocating a larger buffer. But I
do not understand why a (very small value >= a very large value)
results in true, which causes StrAllocSecure to simply return without
allocating the buffer.
Thanks for your comments, I will research it more.
