Comment (by simonmar):

 @erikd the message indicates that somehow the compiled program attempted
 to allocate 1048608 in one go, which is supposed to cause a compile-time
 error.  It is not related to whether the data being processed is static or
 dynamic, but has to do with how the compiled code allocates memory.

 I don't know what's causing it, but it shouldn't be too hard to track down
 - find out which bit of code is causing the offending allocation, and find
 out why GHC didn't detect the overlarge allocation at compile-time.
