The problem is caused by `dmd -v` output, that is parsed and used by rdmd.

$ dmd -v -o- foo.d                
predefs   DigitalMars Posix linux ELFv1 LittleEndian D_Version2 all D_SIMD
D_InlineAsm_X86_64 X86_64 CRuntime_Glibc D_LP64 D_PIC assert D_HardFloat
binary    dmd
version   v2.078.0
config    /etc/dmd.conf
parse     foo
importall foo
import    object        (/usr/include/dmd/druntime/import/object.d)
semantic  foo
entry     main          foo.d
semantic2 foo
semantic3 foo
import    bar   (bar.d)

Calling dmd with -deps option fixes the problem:

$ dmd -v -o- foo.d -deps=/dev/null
predefs   DigitalMars Posix linux ELFv1 LittleEndian D_Version2 all D_SIMD
D_InlineAsm_X86_64 X86_64 CRuntime_Glibc D_LP64 D_PIC assert D_HardFloat
binary    dmd
version   v2.078.0
config    /etc/dmd.conf
parse     foo
importall foo
import    object        (/usr/include/dmd/druntime/import/object.d)
semantic  foo
entry     main          foo.d
semantic2 foo
semantic3 foo
import    bar   (bar.d)
import    baz   (baz.d)

Consequently rdmd command also functions when -deps option is added:

$ rdmd --build-only --chatty -deps=/dev/null foo.d
