OK:
cd / make clean / make distclean / ./configure --enable-static -- 
disable-shared
=> no crash with the patched version of yuvvscaler.c in mac 10.4.11  
intel

Command line:
ffmpeg -i /Volumes/Video_4H/Video_5H/_FICHIERS_A_PROBLEME/SANY0003- 
PAL-60fps.mpg -f yuv4mpegpipe - | yuvscaler -M BICUBIC -O  
SIZE_720x576 >/dev/null
