The leak seems to be in pixmap_put_tile but the bug seems to be in gdk
In the windows binary archive (without X) there is a diff named
freeciv-1.11.4-win.diff.gz (50kB unpacked). Windows binaries without X
and with X are not built from the same source code. As long as the
networking abstraction layer is not in cvs, porting the gtk gui code
changes to cvs is nonsense.
The struct Sprite is different. The source sprites are also stored and
the cropped pixmaps are created by crop_sprite_real. They are only
allocated if they are really needed because windows cannot maintain
many bitmaps. pixmap_put_tile uses the source
That code works on linux without a memory leak. So I think the bug
is in gdk, too.
I have a native windows client (without gtk).
It already has:
a working map window with units blinking (no memory leak)
a connect dialog.
a working menu.
a message window (append_output_window works)
The other dialogs are missing.
It is much faster than the gtk client (esp. scrolling the map).
It works fine with wine (tested with Wine release 20000109 on linux)
and win95. I have not tested it on other windows versions.
When it is a bit more complete I will release test versions and a port
