[meta-freescale] image-prelink (can) cause SIGSEGV on program startup (when run under GDB)

[Julio Cruz Barroso]

Hi Bjørn,

Thanks for your suggestion. 

That was working before. I perform many changes in my image, kernel and update to latest jethro. Not really sure where is the difference.

I will try as below:

1. Full remove of build
2. Go back in jethro and check changes

I let you know the results later.

If you have any chance to test the latest jethro will be appreciated.

Regards

Julio

So it worked before you upgraded to latest jethro? Maybe you can roll
back and/or check the changelog (git log x..y) for the code you just
pulled in?

Also, isn't there a lot of state in build/ beyond build/tmp/ that can
trip up a build? To be really clean, I'd go for full "rm -rf build/".
I'm kind of paranoid about those things :-)

Btw, I'm currently on Yocto jethro branches from mid february, not the
very latest. So maybe there is a real bug in latest jethro...
