-------------------------+-------------------
 Build of ghc fails when trying to install port pandoc.
 A segmentation fault is reported:
         :info:build make[1]: *** [compiler/stage2/dll-split.stamp]
 Segmentation fault: 11

 The OS and software versions are:

         MacBook Air with Mac OS X 10.11.6 (15G1217)
         with current MacPorts 2.4.1

         ports:
         pandoc @1.12.4.2_1 (textproc)
         ghc @7.8.3_5 (lang, haskell)


 The command was:
         sudo port -N install pandoc

 Surprisingly, an installation a day earlier on a MacBook with identical OS
 and software versions was successful.

 Logs are attached.
