Fix Version: 1.3.0
Surprise, surprise ;-)
The proposed patch was not sufficient, since we have two definitions of
fl_xid() depending on the macro FL_INTERNALS and/or FL_LIBRARY.
See attached file fl_xid.cxx for a working test case.
I'm going to fix this now and will commit the changes...

/*
fl_xid() test program (STR #2635)
This program *must* run correctly w/o a crash (segmentation fault)
on all platforms. Watch the output after closing the main window,
this is expected to output "NULL" as the function value.
Note: you should run two tests, one with the following macro
FL_INTERNALS defined and one w/o it. Both must succeed.
Example for a successful run:
$ ../fltk-config --compile fl_xid.cxx && ./fl_xid
...
Line 45: fl_xid(00382ED0) = NULL
Line 52: fl_xid(00382ED0) = NULL
Line 54: fl_xid(00382ED0) = 359F0750
Line 56: fl_xid(00382ED0) = NULL
Note that the last line appears after closing the window.
