--- Comment #43 from Bruno Jesus 00cpxxx@gmail.com 2011-12-17 20:23:52 CST --- Possibly because of the 'poll' word in grep. Retry without it, please. If it's still too big try:
strace -e read wine <app.exe> 2>&1 | grep '= 22' > /tmp/read22only.txt
It will fetch only the read which receives 22 bytes, if it's not there in the end of the process we can be sure wine didn't receive it.
