I miss / in between , and _ZTVN10__cxxabiv120__si_class_type_infoE

$ echo | sed -e 
'/^_*_ZTISt13__ios_failure:/,_ZTVN10__cxxabiv120__si_class_type_infoE/s/_ZTVN10__cxxabiv120__si_class_type_info_ZTVSt19__iosfail_type_info/'
sed: -e expression #1, char 29: unexpected `,'
$ echo | sed -e 
'/^_*_ZTISt13__ios_failure:/,/_ZTVN10__cxxabiv120__si_class_type_infoE/s/_ZTVN10__cxxabiv120__si_class_type_infoE/_ZTVSt19__iosfail_type_info/'
