Thanks for adding the conditions/checks at each return statment, Ian.
I should have suggested removing a couple lines, however -
XFree() must happen at the end of fl_init_xim() whether or not the if
condition fails at 564, so the new/final XFree() call is basically replacing
line 567. I suggest we cut the XFree() at 567 and keep the new check/free at
the end.
New r8278 below.
