hmm, i know that divx4 segfaults if the height isnt divisable through 2 but 
the swscaler can handle that

i cant reproduce it, but i suspect that its caused by the only half 
deactivated mmx code (the runtime cpudetect did ignore the --disable stuff) i 
just fixed that in cvs, so please try again and if its still buggy than 
please send the mencoder output & gdb output of the segfault (with 
./configure --enable-debug ... compiled mencoder)
