When directly serializing C++ structures to a file with the standard
library functions giving the address of the data and length of
structure using the sizeof operator, do I risk portability because of
different compilers packing structures into different sizes or
components of this structure to different address boundaries (for
example placing in multiples of 4 on a 32bit system)? Once the file is
serialized, does the same code compiled by another compiler or even
the same compiler but a different version carry the risk of not
reading the contents properly?

Very much so. Even changing the compile flags can cause
problems. About the only time this works is for temporary
files, which are read and written by the same binary imagine.
