# sanitize flags:

#  -fsanitize=address

# UBSan adds the vptr sanitizer, and V8 exposes polymorphic
# classes (e.g., v8::ArrayBuffer::Allocator) without RTTI
# in the shared library. When we build the JS components
# with -fsanitize=undefined, the vptr checks require typeinfo
# for every polymorphic class; since V8 stripped it, the linker
# trips over typeinfo for v8::ArrayBuffer::Allocator.
# With vptr checks disabled, linking against V8 succeeds, and
# UBSan still covers the other undefined-behavior categories.
#  -fsanitize=undefined -fno-sanitize=vptr

#  -fsanitize=thread
