> `_deh_beg' & `_deh_end' (or should that be da_beg & da_end) are IIRC part of the runtime. Try deleting all the .o files and then running it the other way (gcc -c main.c; dmd test.d main.o) dmd sometimes has issues with stuff if you compile piecemeal. There might be other ways to fix this but I don't recall the details.
