Here's a patch against GDC's phobos/internal/gc/gc.d that fixes the issue.
It was caused by incorrect/missing handling of the "init.length is 0" case in
array resize (the correct behavior is filling with zeroes).

diff ~/gcc/dgcc/d/phobos/internal/gc/gc.d
~/gcc/gcc-4.1.2/libphobos/internal/gc/gc.d

<     assert(initsize);

>     // assert(initsize); // size 0 means fill with zeroes
634c634
<     assert((sizeelem / initsize) * initsize == sizeelem);
---
>     assert(!initsize || ((sizeelem / initsize) * initsize == sizeelem));
