Description Quentin Sculo 2007-10-03 01:07:30 UTC 
Please describe the problem:
Calling $layout->get_iter; leaks memory
I'm using it to get the y position of the first line ($layout->get_iter->get_baseline) so I can align the layout with other things.
Any work-around would be very appreciated.

Steps to reproduce:
By running the attached test program

Actual results:
memory usage grows

Expected results:


Does this happen every time?
yes

test-case program

Running this simple program makes memory usage (as seen by top) grows _very_ rapidly (about 5m per second on my system). Be sure to terminate it with ctrl-C.
One strange thing I just noticed is that changing the timeout value from 1 to 2 or more, _greatly_ slows the growing of memory usage, I've got no idea why.

Plug the leak

Yep, that's a bindings bug.  Fixed in CVS.

I don't know how you'd work around this leak in Perl, unfortunately.
