Hey Richard:
The symbol _end refers to the first location after the uninitialized
data region. Why you're running into this is a puzzle though. On my
IRIX box, here's an interesting note from the man page:
In ISO/ANSI C, the end, edata, and etext symbols are elements of the
space of names reserved for the user. Thus, by default these symbols
are not defined by the loader (ld(1)). If, however, a reference to
end, edata, or etext is unsatisfied during the link, it will be
defined by the loader. The address of the resultant symbol will be
identical to the address of the symbol of the same name prefixed by an
underbar. (Thus, if an unsatisfied reference to end remains at the end
of the link, ld(1) will satisfy the reference by giving it the same
address as _end, which is always defined.)
