I've seen it mentioned (eg in
https://groups.google.com/forum/#!msg/julia-dev/eBwqLqiZSPc/N0QlPMC015EJ)
that Julia can emit DWARF info for Julia functions. This does not seem to
be working for me (see gdb below and cachegrind attached). Is there
something I need to enable, or some dependency I need to update?
