Yep, that's probably the one...  I think the main problem around that
time was that dmd still emitted D arrays as longs.   So of course you
won't get any useful information from gdb.  Giving 2.064 development a
whirl, I see that it has now switched to emitting D arrays as structs
so it strings (and other types of D arrays) should show up with no
problem when debugging code generated by dmd.

I'd recommending checking out the latest development on github, as it
includes some minor fixes to properly highlighting binary numbers,
numbers with optional exponent, wysiwyg string literals r"...", hex
strings x"...", and string postfixes that were added after the 0.6.7
release.
