Hello list,
thank you for helping me to solve my previous post, which found that I
had a memory leak. The solution was to remove uim (universal input
method).
Would you say more about the solution in the list? I am also interested
in it but don't know why there is a leak.
I have a new memory leak problem. This one creates and removes 2000
text entries every 100ms. I've had top showing 64 megs resident after
5 minutes (and no sign of stopping).
If anyone could run the code to see if they get a memory leak (and
post the result) it would be great!
If anyone could shed some light on the problem, even better!
cheers

I've tried this and I had the same results. top is not a leak detector. valgrind, which is what you should be using, shows no leak on GTK's part in this example.
