Comment (by donatello):

 Thank you for the fix, it looks promising - but I am not sure if the
 problem is completely solved.

 The profiling output says that total allocations were reduced from 4.7GB
 to 1.3GB, which is 3.5X improvement. However, the goal in my initial
 program was to embed ~100MB of static data in my program - whereas the bug
 demonstrates the problem with a 3MB embedded string.

 Is there any way I could get a built version of the ghc master for 64-bit
 x86 Linux (from a CI server perhaps), so I could try it out myself?
