hi all
Now i met a strange thing about gtk and moz.
I wrote a simple test program using gtk and gtkmozembed . The attache
file is my test program . It is very simple and short .
I tested the program in Fedora 14 .
Now , i found , when i open the a new link in the gtk browser window,
the test program's VIRT memory is always raising .After open several
links, the VIRT memory reach 3G , then the program becomes no response .
I think the gtk browser should release the VIRT source when opening a
new link , right ?
Does anybody know this issue? And how to fix it ?
thanks
