--- Comment #7 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Now fails with the following backtrace. The location of the failure might have
changed due to the patch at
https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01076.html ; in any case,
currently the failure is:
foo.ii: In member function â__base_dtor â:
foo.ii:11:1: internal compiler error: Segmentation fault
FooWriter::~FooWriter () { delete validator; }
