This reveals:


The mentioned weak symbol is defined in several files:
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_uni.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_math.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_exception.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_conv.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_functional.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_string.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_typetuple.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_container.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_numeric.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_complex.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_array.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_algorithm.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_bitmanip.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_range.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_format.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_utf.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_traits.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_typecons.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_random.o
_D6object15__T8capacityTaZ8capacityFNaNbNdAaZm in std_net_curl.o

but std.stdio is missing. This at least explains it... Thanks.
