Comment (by juhpetersen):

 Replying to [comment:18 erikd]:
 > Using the test program from comment 6 and a basic "Hello world" program,
 I can reproduce this problem by compiling the "Hello world" program with
 `-O2 -dynamic` and running it with the above test program runner.

 I can reproduce with dynamic helloworld too with -O1 and above:

 {{{
 $ cat > test.hs
 main = putStrLn "hi"
 $ rm -f test.o test.hi; ghc -dynamic -O1 test.hs ; echo $(./test)
 [1 of 1] Compiling Main             ( test.hs, test.o )
 Linking test ...

 $
 }}}

 It doesn't happen with -O0.
