Rational Purify reports the following ABW (Array Bounds Write) errors for

[E] ABW: Array bounds write in WideCharToMultiByte {1 occurrence}
        Writing 65535 bytes to 0x001883a4 (65319 bytes at 0x0018847c illegal)
        Address 0x001883a4 is argument #5 of WideCharToMultiByte
        Address 0x001883a4 is 100 bytes into a 316 byte block at 0x00188340

The only place where I can find calls to that API is in 
ACE_Wide_To_Ascii::convert() in $ACE_ROOT\ace\ ace_wchar.inl.  Note that I am 
using ACE 5.2.  I think the problem is that the description for the fourth 
argument (cchWideChar) to WideCharToMultiByte() has changed.  It used to
