Hi,
In order to answer to the 37231th article in comp.lang.c group, I rewrite some
part of the initial article.

In this program the declaration of end() is ambiguous because it also refers to
standard routines :
extern end; This name refers neither to routines nor to locations with
interesting contents. The address of end() is the first address above the
uninitialized data region.
When execution begins, the program break (the first location beyond the data)
coincides with end, but it is reset by the routines brk, malloc, standard
input/output and so on.
So a simple solution would be to change the name of your eeeeeennnnnnnnnddddddd.
Good receive.
