Re: Memory leaks in Pango ?

[Olivier Fourdan <fourdan xfce org>]

Hi all,

Well, I might be fooled by memprof actually. I've let the process run
for about 1 hour and memprof was reporting about 65Mb of memory usage
(!) for gtktest

But, if I actually look at which process consumes memory, well, it's
memprof.

So, I conclude the problem is with memprof wrongly reporting process
memory usage.

How reliable is memprof ?

Cheers,
Olivier.
