Maybe some part the leaks come from the Xlib. I think that the
debian package is compiled with --enable-multibyte. There is some memory
leaks in XCreateFontSet: each time a font is unloaded ~4kb is lost (this
depends on the font, with an utf8 locale and if you use an iso106464-1
font with a big coverage this may be a lot more).
For example:
- if you delete a window ~4kb is lost (0kb with 2.5.2)
- if you change your font and you have 20 windows, ~80kb is
lost (only 4kb with 2.5.2).
I've recently sent a patch to the XFree developers but no feedback yet ...
Note that I do not claim that all the leak come from the Xlib,
it is just a possibility. So one question and one query:
- Do you do something special regarding the fvwm config
(as regularly changing some config parameters)
- Can you send me your config file(s) if this is possible.
