Oh, indeed. I missed that because it didn't start with the long hex address. > So, as far as I can see, the gdb stacktrace is similar with -O1 and -O2 > (if we ignore small details like the namespace taehdf5::) Yes. But that makes it even more confusing to me: apparently gdb picks up the debug information about the inlined function just fine - but valgrind doesn't. I'll update valgrind to most recent and see if I can explicitly disable inlining.
