Comment (by osa1):

 Thanks for simplifying the code.

 I made an attempt at removing unboxed sums (and had to remove some unboxed
 tuples on the way) [https://github.com/andrewthad/corrupted-memory-
 example/pull/1 here], and that made the bug disappear. So this may be
 related with unboxed tuples/sums.

 > If I use my parser language to simply build up a parser, and then I run
 the parser

 Can you elaborate on this? What do you mean by building your parser
 language? Can you share the code?
