[lldb-dev] New Failure TestCallStdStringFunction.test_with_dwarf just started failing in top-of-tree

[Pavel Labath]

So the problem seems to be related to -fstandalone-debug (at least one part
of it). Right now there is a problem, where -fstandalone-debug and
libstdc++-dbg cannot coexists for whatever reason:
-fstandalone-debug, libstdc++-dbg uninstalled -> test works fine
-fno-standalone-debug, libstdc++-dbg installed -> test works fine
-fno-standalone-debug, libstdc++-dbg uninstalled -> failure, cannot find
std::string definition [as expected]
-fstandalone-debug, libstdc++-dbg installed -> failure, for whatever reason
we end up calling std::random_device::_M_init() instead of
std::string::c_str() [bad]
