+
+fix a memory leak in XRegisterIMInstantiateCallback
+
+Analysis:
+
+ _XimRegisterIMInstantiateCallback() opens an XIM and closes it using
+ the internal function pointers, but the internal close function does
+ not free the pointer to the XIM (this would be done in XCloseIM()).

+ Subject: Re: Yet another leak in Xlib
+
+ For reference, here's how I'm calling XRegisterIMInstantiateCallback:
+
+ XSetLocaleModifiers ("");
+ XRegisterIMInstantiateCallback (compositor.display,
+ XrmGetDatabase (compositor.display),
+ (char *) compositor.resource_name,
+ (char *) compositor.app_name,
+ IMInstantiateCallback, NULL);
+ and XMODIFIERS is:
+
+ @im=ibus
