[Buildroot] Howto track/trace segfaults on ARM ?

[Buildroot] Howto track/trace segfaults on ARM ?

[Vellemans, Noel]

Hi,

Probably not the GOOD place to ask for this information, but.. Going to
give it a shot.

I'm still working on WebKit-1.6.3 for buildroot (which seems to work ,
at least , I get in compiled..)

FYI: I'm cross-compiling for ARM (imx537).
 
But, when running the WebKit Code (GtkLauncher, which is a
mini-WebKit-browser) I get a lot of crashes / segmentation faults /
aborts.

Is there somebody that can point me in direction on how to find/trace
these segmentation faults ... ???? 

I would like go go deeper into detail in order to find the crashes.


All hints are Welcome,
Thanks.


PS: If I do the same build on a native PC (x86) then it does not
segfault.

Load the core file into gdb and type "bt".

You'll need to have built with debug symbols and you need to run gdb
where it has access to the un-stripped object files (and prefereably
the source trees of the programs in question).
