Re: Using "GHC as a library" with own functions makes runStmt return RunBreak

Hi
I am trying to use "GHC as a library". From runStmt, I want to load and run
functions from a home-grown module. Lets call my home-grown module 
HomeGrown.hs.
I have tried to model my application after 
http://haskell.org/sitewiki/images/1/17/Interactive-6.8.hs /
http://haskell.org/sitewiki/images/f/f9/MyPrelude.hs from
http://haskell.org/haskellwiki/GHC/As_a_library . This library loads
MyPrelude.hs and runs myPutStrLn & myGetLine + more.
However, when I try to run code from HomeGrown.hs like:
runStmt session "HomeGrown.foo" GHC.SingleStep
runStmt keeps returning RunBreak (of type RunResult). From what I can read of
the WWW, RunBreak is related to some debugger and indicate that GHC 
encountered
some breakpoint. However, I did not set any break points.
For those interested I figured out how to avoid the RunBreak -returns.
Use RunToCompletion in stead of SingleStep in the application of runStmt.
I guess Interactive-6.8.hs should also use SingleStep. 

Greetings,
