libX11/U_fix-a-memory-leak-in-XRegisterIMInstantiateCallback.patch
Stefan Dirsch b512dabc48 - going back to version 1.7.5 for now to get rid of regressions,
which were introduced by trying to get thread-safe in libX11
  itself 
- re-introduced U_fix-a-memory-leak-in-XRegisterIMInstantiateCallback.patch
  which was not yet in 1.7.5

Subject: [PATCH] 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
