Re: Memory leaks in Pango ?

["Richard Warren" <rew primagraphics co uk>]

Hi Olivier,

What version of GTK are you using?  Are you up to date?

I used to see memory problems when repeatedly changing the text in labels
before the V2.0.0 release came out.  It certainly happened with V1.3.9 but
was fixed sometime before V1.3.14.  (It still happens on the Win32 version
though).

Richard.
