[Serdev] ser on arm, crashed.

[wpu220]

I have built ser-0.9.6 for ep9315( core arm920t)
first I cross compiled libfl.a,
then make ARCH=arm OS=linux OSREL=2.4.21-rmk1-crus1.4.5 CC=arm-linux-gcc  
all
There is a lot of warnings,while compiling,
such as cfg.y: conflicts: 1 shift/reduce
or avpops.c:653: warning: cast increases required alignment of target type
or /usr/local/arm/3.3/lib/gcc-lib/arm-linux/3.3/ld: Warning: alignment 4  
of symbol
`pid_file' in main.o is smaller than 32 in msg_translator.o

The make completed without errors and Ser run successful on the arm,with  
the default cfg(ser -f ser.cfg) .
But when I tried to regist to the ser, the ser crashed with segmentation  
fault.
what I did is wrong? The compile method£¿The way run ser?help me,please.
