We do call interceptors by that name in few places in our internal code base. Also, if you remove them, then symbolizer won't be able to print anything at all, which does not look better. Btw, tsan strips __interceptor_ prefixes. Which is actually another use of __interceptor_ symbols. -- You received this message because you are subscribed to the Google Groups "address-sanitizer" group.
