ldionne added a comment. Sorry, I read this last week and probably forgot to reply.
I think the right thing to do is to fix the UB, which appears to mean fixing libc++. However, can you take a look at whether defining these macros help? // Fix undefined behavior in how __tree stores its end and parent nodes. # define _LIBCPP_ABI_TREE_REMOVE_NODE_POINTER_UB // Fix undefined behavior in how __hash_table stores its pointer types. # define _LIBCPP_ABI_FIX_UNORDERED_NODE_POINTER_UB # define _LIBCPP_ABI_FORWARD_LIST_REMOVE_NODE_POINTER_UB # define _LIBCPP_ABI_FIX_UNORDERED_CONTAINER_SIZE_TYPE We have some known UB in our container types, but fixing that UB is an ABI break, so it's only enabled when some specific macros are turned on. I think you might be hitting that.
