strange test in line 73: if (!(size = sizeField(arg))) size = argByteSize = sizeof(void *); else argByteSize = abs(size);

for me, it means

                    if (sizeField(arg) != 0)
                            size = argByteSize = sizeof(void *);
                    else
                            size = argByteSize = 0;

you have it the wrong way round. It is equivalent to

                    size = sizeField(arg);
                    if (!size)
                            size = argByteSize = sizeof(void *);
                    else
                            argByteSize = abs(size);

which is equivalent to

                    size = sizeField(arg);
                    if (size == 0)
                            size = argByteSize = sizeof(void *);
                    else
                            argByteSize = abs(size);

...

is it intentional ?

Hem, my bad, as most humans, my logic failed at double negation...

if( size ) <=> if (size != 0) if( ! size ) <=> if (! (size != 0)) <=> if (size == 0)

Eliot, this indicates that you and your code are too clever ;)

Nicolas

yes.
