# MB-49880: "runtime error: member call on address 0x60d000000380 which does not point to an object of type 'v8::Platform'"
# Suppress this issue while being investigated, as to not cause CV to fail
# for other jobs.
vptr:std::default_delete<v8::Platform>::operator()(v8::Platform*)

# Similar to previous suppression - V8 v10.7.21 uses shared_ptr for
# v8::internal::Isolate* objects and we do not have necessary RTTI
# type info in our libv8 for UBSan to be able to check vptr matches.
# This results in warnings of the following when running couchstore
# views unit tests:
#     shared_ptr_base.h:155:46: runtime error: member access within address 0x60c000000a00 which does not point to an object of type 'std::_Sp_counted_base<__gnu_cxx::_S_atomic>'
