 On my `x86_64` Windows machine test `prog003` fails with a segfault:

 (I do not think it is an access violation error since when I remove
 [https://github.com/ghc/ghc/blob/c2fab84239299176a8e72aa26ae894019d677bd9/testsuite/tests/ghci/prog003/prog003.script#L65
 line 65] and everything below line 70, the same stdout is generated.)

 This looks related to ticket #11234.

 The GHC version used was
 [http://git.haskell.org/ghc.git/commit/df6cb57b32d94b7f6f7c9a86207adfeee9712ed6
 df6cb57b32d94b7f6f7c9a86207adfeee9712ed6], although I already noticed the
 problem with a version a few days older.

 If someone could point me to information about how to install GDB suitable
 for debugging GHC on my Windows machine I will try to post the stack
 trace.
