Please, read freetype2/docs/DEBUG: building 2.1.8 and 2.1.7 with 
FT_DEBUG_LEVEL_TRACE 
defined; and run a web browser with "export FT2_DEBUG=any:9".
Comparing the debug output of 2.1.8 and that of 2.1.7, I hope we can do 
something.

Of course, gdb's backtrace is also good.
---------------------------------------------------------------------------
  FT2_DEBUG

    This   variable  is   only  used   when  FreeType   is   built  with
    FT_DEBUG_LEVEL_TRACE defined.  It contains a list of component level
    definitions, following this format:

       component1:level1 component2:level2 component3:level3 ...

    where "componentX" is the name of a tracing component, as defined in
    "fttrace.h",  but  without the  "trace_"  prefix.   "levelX" is  the
    corresponding level to use at runtime.

    "any"  is a  special  component  name that  will  be interpreted  as
    "any/all components".  For example, the following definitions

       set FT2_DEBUG=any:2 memory:5 io:4        (on Windows)
       export FT2_DEBUG="any:2 memory:5 io:4"   (on Linux with bash)

    both stipulate that  all components should have level  2, except for
    the memory  and io components  which will be  set to trace  levels 5
    and 4, respectively.
