Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jwakely.gcc at gmail dot com --- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> --- Looks like this is (also) a runtime issue: normally works on clang, but does *not* if -stdlib=libstdc++ is added to the command line. Futher evidence: does not work with icc, which uses the system runtime, but works with eccp.
