Comment(by edsko):

 The above output without gdb is on ghc 7.6.1; on ghc 7.4.1 it is slightly
 different:

 {{{
 Running "InvalidAddress": *** Exception (reporting due to +RTS -xc):
 (THUNK_2_0), stack trace:
   Network.Transport.TCP.Mock.Socket.getAddrInfo,
   called from Network.Transport.TCP.Internal.forkServer,
   called from Network.Transport.TCP.createTransportExposeInternals,

   called from Main.testInvalidAddress.\,
   called from Main.testInvalidAddress,

 }}}

 Note sure that's in any way informative, but I thought I'd mention it
 anyway.
