--- Comment #6 from Adrian Cheater <adrian.cheater at gmail dot com> ---
Hi, I'm also having this problem.

In my case, I'm observing that the mangled string

"_ZNSt9_Any_data9_M_accessIPZN6cereal18polymorphic_detail15getInputBindingINS1_16JSONInputArchiveEEENS1_6detail15InputBindingMapIT_E11SerializersERS7_jEUlPvRSt10unique_ptrIvNS5_12EmptyDeleterIvEEEE0_EESA_v"

Seems to get stuck in an infinite loop, and after 6 flushes of the buffer to
the growable buffer, that buffer looks like this"

"cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cerea"

I'm going to assume that there's a bug in the dc tree parser or walker? I'm
very new to this and I guess my next step is to read the ABI and see what the
correct demangling of that string should look like, that should give me some
idea of where to look for where it goes off the rails.
