Hi,
attached is a simple test application that calls gtk_label_set_text()
from a timeout. top and memprof show that the application (linked
against gtk+-1.3.8 running under X11) leaks memory like hell. I found
a leak in pango (see my previous mail), but it's obviously not the
only source of leakage. Perhaps posting the test application here
helps to track the problem down.
Salut, Sven
