The dmd package on NixOS doesn't work anymore in their master

Since dmd still works correctly on the stable branch I tried to
examine the differences of libphobos2.a.
I switched back to version 2.079.0 on master to have the same
version as on stable.
First I diffed the outputs of 'ar -t libphobos2.a' but there
weren't any differences.
But executing 'nm libphobos2.a' results in many errors like:
nm:
/home/thomad/devel/nixpkgs/result/lib/libphobos2.a(object_1_257.o): no group info for section .text._D6object6Object5opCmpMFCQqZi
nm:
/home/thomad/devel/nixpkgs/result/lib/libphobos2.a(object_1_257.o): no group info for section .text._D6object6Object5opCmpMFCQqZi
nm: object_1_257.o: Bad value
nm:
/home/thomad/devel/nixpkgs/result/lib/libphobos2.a(object_5_391.o): no group info for section .text._D6object9Interface9__xtoHashFNbNeKxSQBjQBfZm
nm:
/home/thomad/devel/nixpkgs/result/lib/libphobos2.a(object_5_391.o): no group info for section .text._D6object9Interface9__xtoHashFNbNeKxSQBjQBfZm
nm: object_5_391.o: Bad value
nm on the static lib of the stable branch has just one error:
nm: threadasm.o: no symbols
Looking into the output of both nm calls shows that a lot of
sections are missing in the static phobos lib on the master
branch.
The first being object_1_257.o.
Now I wonder how something like that is possible.
