Ubuntu 10.04.3 LTS mapserver shp2img hang

[Min Wang]

HI
     On Ubuntu 10.04.3 LTS (AMD64) ,  I tried to use shp2img ( because 
mapserver seems not working, so try to debug it use shp2img etc), it 
seems shp2img hang somewhere.

     futex(0x80db90, FUTEX_WAIT_PRIVATE, 2, NULL )

     see the below:

close(3)                                = 0
futex(0x80db90, FUTEX_WAIT_PRIVATE, 2, NULL

(2) On Ubuntu 11.10
    the same command/configure runs well.


     Any clue? or Is the mapserver on 10.0.4.3 lucid usable?



Thanks
