H264 streaming broken in 0.9/1.0 on win32 when H264 compiled with pthread

h264 streaming crashes. Sample code to reproduce:

--reset-config --no-qt-privacy-ask --high-priority "G.mpg"
--extraintf logger -vvv --no-stats --sout-transcode-threads 1 
:sout=#transcode{scale=1,vcodec=h264,venc=x264,vb=300,acodec=mp3,
ab=64,channels=2}:standard{access=http,mux=ts,dst=:8080}

Ruled out scale and thread issues by both setting to 1. Also happens with:

• input mmsh wmv and udp/ts mpeg2.
• acodec mp4a and --no-audio
• output mmsh/asfh with same settings

Change codec to DIV3 and the commandline works, otherwise it crashes. Last thing I see in normal log:

Last thing I see in extraintf logger is the detection of CPU capabilities by x264.

Rumoured to work ok on non-win32. Backtrace in progress.. Feel free to add comments if it does work for you :)
