I said *modulo the pace size* :-)
Lets say ld thinks the page size for your system is 1Mb (nor an unreasonable
assumption). The vma of .text is aligned on a 1Mb boundary. In order to
allow loading via mmap, the location of .text within the file must also be
aligned on a 1Mb boundary. It can't put it at address zero because the ELF
headers get in the way, so the first viable location is 1Mb into the file.
