[Haskell-cafe] options for the RTS in a dll

I've written a windows dll in Haskell. The calling program is written in
Delphi (pascal). I want to profile this dll.
Because you don't have a command line in a dll for +RTS. -RTS, I call the
dll with hs_init_ghc (a exported function in the dll). I had to translate
some parts of rtsopts.h to Delphi.
Everyting seems okay. The program does not hang, no catastrophic failures.
When I start with the parameter for rtsoptions in hs_init_ghc I get:
with -t --machine-readable ->machine readable overview on the screen.
with -B sounds the bell with each garbage collection,
and also --info works as expected.
But when I call hs_init_ghc with rtsoptions -h I get 3 lines with on each
line: Can't open profiling report file <unknown>.hp.
With -p I get missing profiling report <unknown>.prof
Any idea what I'am doing wrong?
