Subject [jira] Commented: (AXISCPP-920) Use of deleted pointer in NonPositiveInteger::serialize
Date Thu, 26 Jan 2006 09:36:14 GMT
    [ http://issues.apache.org/jira/browse/AXISCPP-920?page=comments#action_12364072 ] 

Adrian Dick commented on AXISCPP-920:
-------------------------------------

I'm a little confused as to what code you're currently using.

It appears to me that you're working with the code in the old CVS repository, rather than
the SVN repository - the web services projects migrated across at the end of August.

Looking in the SVN log, the section of code above was removed in September, as can be seen
here: http://svn.apache.org/viewcvs.cgi/webservices/axis/trunk/c/src/soap/xsd/NonPositiveInteger.cpp?rev=280324&r1=264831&r2=280324&diff_format=h

Instructions for obtaining the latest code from SVN can be found here: http://ws.apache.org/axis/cpp/developers-guide.html#checkingOut

> Probably line 161 should read

> or maxInclusive should not be deleted until later.
> I would recommend use of std::auto_ptr to keep track of memory allocation here,
> which has the added benefit of making the code exception safe. Note that this file has
> numerous memory leaks in case an exception is thrown!
