strange test in line 73:

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 ?

yes.
