Hi all, I am a newbie working on reducing the memory footprint of GTK
applications for use on a cell phone. Does anyone know what some of this is?
Here is a pmap Of a trivial gtk app (think hello world with buttons). These appear to be memory segments with no permissions. They
are too big to be guard pages. 40507000 28K -----

/usr/lib/libpangoft2-1.0.so.0.801.1 There are also anon segments. I have not looked into them
yet but I suspect they are malloc()’d or memory mapped files. /bin # pmap 1125 1125: bar:com.access.apps.duck 00008000 12K r-x--
