Does FPC ensure the same memory alignment for records and objects
over different platforms?
No, alignment is defined by the platform ABI.
If I want to be sure to have the same
alignment must I use packed (with possibly some aligning assigned)
records instead in combination with data types that are guaranteed
to be
of the same size over the different platforms (eg byte, word,
single) ?
Yes.
When
memory is alligned (either with {$PACKRECORDS N} or unpacked, are the
padding bytes quaranteed to be #0 or are they undefined?
They are undefined.
