Comment (by sergv):

 {{{
 Question do all the machine it segfaults happen on are all equipped with
 Cygwin?
 }}}

 No, I opened this issue after trying on a virtual machine without Cygwin.
 I have removed Cygwin and tried again - crash is still there in msys 2.0.

 {{{
 I'll really need a dump or a linker log, but the latter requires a debug
 version of GHC.
 }}}

 For some reason crash dumps are not collected, even though I followed the
 instructions you linked. I can try building a debug version of GHC and get
 it a go. Is this the right instructions to obtain debug ghc
