it's fully reproducable in number of x86_64 systems:
system "1",glibc-core-2.25-alt2.x86_64, AMD Athlon, kernel 4.9.56
system "2",glibc-core-2.25-alt3.x86_64, Core i5, kernel 4.9.56
system "3",glibc-core-2.25-alt3.x86_64, Core i7, kernel 4.9.42
system "4",glibc-core-2.25-alt3.x86_64 ,Xeon E5-2620, kernel 4.9.65
with the same behavior, so it is not installation -- dependent.
all previous versions of dmd works good.
ldc2 1.7.0-beta1 and older works ok as well.
all another functionality, except of fwrite, seems to be ok.
