--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
When I step through std::rethrow_exception() in gdb it goes from line 215 to
line 223, so skips over the call to get_terminate(), so dep->terminateHandler
is null and so is dep->unwindHeader.exception_cleanup

(gdb) bt
#0  std::rethrow_exception (ep=...) at
/home/jwakely/src/gcc/gcc/libstdc++-v3/libsupc++/eh_ptr.cc:223

out>) at ep.cc:19

(gdb) p *dep
$17 = {primaryException = 0x603090, unexpectedHandler = 0x7ffff7d3a7c0
<std::terminate()>, terminateHandler = 0x0, nextException = 0x0, handlerCount =
0, handlerSwitchValue = 0, actionRecord = 0x0, languageSpecificData = 0x0, 
  catchTemp = 0, adjustedPtr = 0x0, unwindHeader = {exception_class = 0,
exception_cleanup = 0x0, private_1 = 0, private_2 = 0}}
