It's weird that we're failing there. If we're looking at a buffer with
dumped contents, we set b->text->beg to NULL, then use the normal
buffer-allocation procedure (whichever we're compiled to use) to
allocate memory for the contents. How can the resulting address ever be
equal to what we started with? Neither mmap_realloc nor r_re_alloc nor
xrealloc should ever reuse the address.
