memory waste under certain circumstances

[Markus Rechberger]

Hi Luca,

if possible contact us via Skype (sundtek). The information is not really
enough, if you write that you are using cat and piping it into your
application it doesn't really matter where the data comes from.
Can you run your application on a x86 PC with eg. valgrind?

Best Regards,
Markus
