Possible bug in PHP 5.1 b3 SOAP extension

[Jure Erznožnik <jure.erznoznik@jantar.si>]

I have a custom SOAP server (programmed in Delphi 7.0)

One of the functions is:
 base64Binary ExportData(int User, string Data, string FormatParams)

<message name="ExportData11Request">
<part name="User" type="xs:int"/>
<part name="Data" type="xs:string"/>
<part name="FormatParams" type="xs:string"/>
</message>
<message name="ExportData11Response">
<part name="return" type="xs:base64Binary"/>
</message>

The function is meant to return binary data, in this case a PDF file.

With PHP 5.0.5 SOAP extension, this function worked fine, with 5.1 however,
it doesn't work as expected (the string returned is corrupted, not to
mention too short).

  $SOAPClient = new SoapClient(SOAPServer);
  return $SOAPClient->exportData(userId(), $data, $formatParams);  <-- Tried
this one
  return mb_convert_encoding($SOAPClient->exportData(userId(), $data,
$formatParams), "ASCII", "UTF-8"); <--Tried this one too
  return mb_convert_encoding($SOAPClient->exportData(userId(), $data,
$formatParams), "ASCII", "BASE64"); <--This one works with PHP 5.0.5

I use mbstring extension with internal encoding set to utf-8 (attaching
php.ini)

I have determined that the problem is in the function to_zval_base64
(php_encoding.c), which employs some new functions transferred to
ext/standard/base64.h (this include is not in 5.0.5 source). I'm guessing
that the functions in the base64.h (c) use mbstring extension and therefore
return a result which is modified from the original binary source.

Reverting to 5.0.5 solves the problem.
