jemalloc on iMX6 ARM

[Jorge Fernandez Monteagudo]

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

https://github.com/jemalloc/jemalloc/tree/master

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/libjemalloc.so.2 root@<imx6_board_ip>:/tmp/

when I tried in the board I get:

# export LD_PRELOAD=/tmp/libjemalloc.so.2
# 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/libjemalloc.so.2 root@<imx6_board_ip>:/tmp/

when I tried in the board I get:

# export LD_PRELOAD=/tmp/libjemalloc.so.2
# 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
