--- Comment #1 from Rainer Schuetze <r.sagitario at gmx.de> ---
The TLS directory is not generated into the executable. It's not linked in
because there is no reference to _tls_index in the object file as dmd assumes
_tls_index==0 when directly building an executable.

If you compile with -c and link separately, the TLS directory exists and the
program runs without problems.
