jemalloc on iMX6 ARM

Hi all, this is my first post to this mailing list.

I'm trying to give a try to jemalloc in a iMX6 ARM board. I've
downloaded the current master image from

I've done the cross compilation with no problem and I've deploy
the lib to the board. Our iMX6 image is using 3.14 linux kernel.
The library generated with

./configure --build=x86_64-linux --host=arm-poky-linux-gnueabi
scp lib/ root@<imx6_board_ip>:/tmp/

when I tried in the board I get:

# export LD_PRELOAD=/tmp/
# ls
Bus error

and in dmesg I can see

Alignment trap: not handling instruction e1b14f9f at [<76f06b14>]
Unhandled fault: alignment exception (0x011) at 0x76f2cfe4

If I build the library with

./configure --build=x86_64-linux --host=arm-poky-linux-gnueabi --disable-fill
scp lib/ root@<imx6_board_ip>:/tmp/

when I tried in the board I get:

# export LD_PRELOAD=/tmp/
# ls
Segmentation fault

I guess the jemalloc is able to work on ARM systems. Where should I start looking to
make it work? Any hint is welcome!

Pd: This is the configuration the 'configure' process prints on screen
