I found the problem.
Nix is stripping the libs and binaries on installation and there seems to be a
bug introduced in binutils 2.30 with strip.
I disabled the striping and everythings worked fine.
You can find the unstripped lib here:

Output of nix-build when stripping:

strip is /nix/store/j75dgadrff2d1fyc4fczmcgqkid2imdx-binutils-2.30/bin/strip
stripping (with command strip and flags -S) in
/nix/store/q674hw91v3605szwhhc8ypwdc2iqxb20-dmdBuild-2.079.1/lib 
/nix/store/q674hw91v3605szwhhc8ypwdc2iqxb20-dmdBuild-2.079.1/bin
