>             Project: Axis2-C
>          Issue Type: Bug
>          Components: code generation
>    Affects Versions: 1.4.1
>         Environment: Win32
>            Reporter: Mirko Wischer
>            Priority: Minor

> The xslt used for transforming to C Code (CADBBeanTemplateSource.xsl) creates 
> a memory leak:
> Code created for adb_..._serialize(..) contains a memory leak for the 
> following types:
> - axutil_date_time_t
> - axutil_base64_binary_t
> The XSLT uses axutil_base64_binary_get_encoded_binary() and 
> axutil_date_time_serialize_date_time() for creating
> textual representations. After writing these texts to the stream the start 
> and end tags are freed but the
> the generated code never releases the base64 text or data_time text:
> Look at the follown snippet from the trunk version of the XSLT:
> (starting at Line: 4435)
>                         <xsl:when 
> test="$nativePropertyType='axutil_date_time_t*'">
>                           text_value_<xsl:value-of select="$position"/> = 
> axutil_date_time_serialize_date_time(<xsl:value-of 
> select="$propertyInstanceName"/>, env);
