>                 Key: XERCESC-1702
>                 URL: https://issues.apache.org/jira/browse/XERCESC-1702
>             Project: Xerces-C++
>          Issue Type: Bug
>          Components: Utilities
>    Affects Versions: 2.0.0, 2.1.0, 2.2.0, 2.3.0, 2.4.0, 2.5.0, 2.6.0, 2.7.0
>         Environment: Windows XP (but I am sure this will fail for Cygwin as well).
>            Reporter: Ozgur Sahoglu
>             Fix For: 2.7.0
>
>
> Steps to reproduce:
> 1. Open the registry editor in Windows (regedit.exe).
> 2. Goto HKEY_CLASSES_ROOT\MIME\DataBase\Charset\<any_charset>/AliasForCharset
> 3. Delete the Value Data, but don't delete the key
> 4. Run any app that uses Xerces-C
> The problem is in src/xercesc/util/Transcoder/Win32/Win32TransService.cpp file. In version 2.7 goto line # 371:
> const unsigned int targetLen = srcLen/charLen;
> if charLen is 0, then you get Divide_By_zero exception.
> I changed line #370
> from 
> if (charLen != -1) {
> to
> if (charLen > 0) {
> to fix it.
