Subject: Re: [Tinycc-devel] Segmentation Faults and test failures on ARM
(Raspbian/Raspberry Pi)
Hi Thomas:
I am running a test script now on the Raspberry Pi using your latest push.
So far (10 runs or so), so good....
I will update the list with more results in a while.
Regards,
Jerry

I managed to do a quick push. Please try extensively. I'll see for the
header issue on the raspbian as soon as I have a better connectivity.
