Comment:

 With GHC 8.2.2 and GHC 8.4.4 I get the same result as @lierdakil above:

 {{{
 roland at goms:~/Projekte/ghctest/T14950$ ghci
 GHCi, version 8.4.4: http://www.haskell.org/ghc/  :? for help
 Prelude> :l T14950.hs
 [1 of 1] Compiling Test             ( T14950.hs, interpreted )
 Ok, one module loaded.
 *Test> :break test
 Breakpoint 0 activated at T14950.hs:3:8-16
 *Test> :trace test
 Stopped in Test.test, T14950.hs:3:8-16
 _result :: IO () = _
 [T14950.hs:3:8-16] [T14950.hs:3:8-16] *Test>
 }}}

 However with GHC 8.6.1 and higher (8.6.2 and GHCHEAD-8.7.20181124) there
 is no more a double prompt:


 {{{
 GHCi, version 8.6.1: http://www.haskell.org/ghc/  :? for help
 Prelude> :l T14950.hs
 [1 of 1] Compiling Test             ( T14950.hs, interpreted )
 Ok, one module loaded.
 *Test> :break test
 Breakpoint 0 activated at T14950.hs:3:8-16
 *Test> :trace test
 Stopped in Test.test, T14950.hs:3:8-16
 _result :: IO () = _
 [T14950.hs:3:8-16] *Test>
 }}}

 Hence, this has been fixed!
