Using multibyte and Adrey's config file I did see a growing fvwm2 and
Purify reported these at termination:
MLK: 24576 bytes leaked in 8 blocks
* This memory was allocated from:
malloc [rtlib.o]
_XQueryFont [Font.c]
XLoadQueryFont [Font.c]
load_font [XSunOMIF.c]
create_fontset [XSunOMIF.c]
create_oc [XSunOMIF.c]
XCreateOC [OCWrap.c]
XCreateFontSet [FSWrap.c]
GetFontSetOrFixed [GetFont.c:65]
LoadFvwmFont [GetFont.c:106]
setup_icon_font [add_window.c:378]
AddWindow [add_window.c:1307]
HandleMapRequestKeepRaised [events.c:1035]
HandleMapRequest [events.c:999]
DispatchEvent [events.c:2766]
HandleEvents [events.c:2819]
main [fvwm.c:742]
_start [crt1.o]
* Block of 3072 bytes (8 times); last block at 0x324d38
I don't normally use icon titles so I might have missed them
in previous tests. Also I'm not sure if leaks at termination
are really leaks, if you are going to exit, theres no point in
freeing things. It does look like there were 8 icon fonts allocated.
Thats close to the number of windows I created.
