When I try to compile this code with 'dmd main.d', I get errors
main.o: In function
`_D4core7runtime7Runtime17__T11loadLibraryZ11loadLibraryFxAaZPv':
main.d:(.text._D4core7runtime7Runtime17__T11loadLibraryZ11loadLibraryFxAaZPv+0x4d):

But it's built without errors when I separate compile and link
parts:
dmd -c main.d
gcc main.o -lphobos2 -o main
I checked libraries with nm utility and actually found no such
symbols in static version of libphobos. But shared one has
these symbols.
Well, I'm aware of that runtime loading requires shared version
of phobos2 to avoid duplicating of D runtime. But why does dmd
use static linking by default? Is shared version of phobos
still experimental? Anyway we need some remarks in
documentation about the lack of these functions in static
version of phobos.
This seems like a weird change if intentional, since the function
is publicly declared. I'd file a bug report.
