Hi Gents,

I will give it a crack and have a wee' browse at it. I have tried all sorts of hacks so far without going into mysqlpp all to no avail.

Thanks, Garyc --- Matt Dargavel <ma@shout-telecoms.com> wrote:

Hi Gary,

This sounds like the leak Alex and myself looked at a while ago (see thread at http://lists.mysql.com/plusplus/5767 ). Warren implemented a patch for it (see thread at http://lists.mysql.com/plusplus/6012 ). I'm not sure it's been released yet, but it's available from svn.

Regards,

Matt.

Hello,

Not sure what is going on but I think I have found the memory leak when running on windows using the purify tool from IBM.

I see Memory leak when calling the below code. new(UINT)

[f:\rtm\vctools\crt_bld\self_x86\crt\src\xiosbase.514]

std::ios_base::Init(void)[f:\rtm\vctools\crt_bld\self_x86\crt\src\xiobase

std::basic_ios<char,char_traits<char>::std>::init(basic_streambuf(char,char_traits<char>::std>::std

*,bool)

Ok this is why the leak occurred. I was using the below statement.

mysqlpp::Query query = con.query();

The query is being created every time which inturn creates an ostream which results in a leak. The query object I now pass as a reference and then reset the blighter which avoids the leak since only instantiated once.

Thanks, Garyc
