Seeing this late, but the dmd compiler itself was never a GC'ed 
program.  The frontend was written in C++ then mostly 
automatically translated to D, and the old manual allocation 
scheme was kept. To make it actually work with GC for the first 
time would probably require some work, same for your library.

The good news is your library is @nogc for free! ;)
