Packfile writing bug

[Jonathan Worthington]

Hi,

I seem to be touching a bug related to writing compiled code.
pir_comp = compreg "PIR"
pbc_out = pir_comp(gen_pir)
fh = open output
print fh, pbc_out
close fh

On the print line, I get this error:-

directory_pack segment 'BYTECODE_EVAL_1' used size 158 but reported 160

This used to work - I sync'd up my Parrot tree from one that's at least a 
week old and it was broken, however.  So I guess the outcome or a recent 
change.

Fixes very welcome,

Jonathan
