--- Comment #2 from Henry Hu <henry.hu.sh@gmail.com> ---
I have a similar problem:
pipelight-flash works for simple flash sites and audios, but crashes for video
sites. In dmesg, you see "pid xxxx (wine), uid xxx: exited on signal 10"

This method fixes the issue for me, you may have a try:

Set CFLAGS=-O0 -mstackrealign in make.conf, and rebuild 32 bit libthr.so.
You may do it in this way:

cd /usr/src
make build32
echo "CFLAGS+=-mstackrealign -O0" >> /etc/make.conf
make build32
make install32
(or just install libthr.so manually

The core file points me to a movsd instruction in libthr.so. I'm not sure if
movsd has alignment requirements, but -mstackrealign does not fix it. With -O0,
movsd is not generated, and youtube works....
