      With GCC and Clang we disable exceptions and RTTI when compiling C++. On Windows we currently do not disable RTTI. In https://github.com/openjdk/jdk/pull/12073 I tried to do so, but for some unknown reason it causes a subset of serviceability agent tests to fail. The exact reasoning is unknown. It seems to have something to do with either DbgHelp or DbgEng, but that is a guesstimate. We should figure out what is going on so we can eventually disable RTTI on Windows, which will reduce the binary size for Hotspot by at least 1 MB.

      The tests in question that fail are:

      serviceability/sa/ClhsdbCDSJstackPrintAll
