Hi Rene, I also have an RPi2 here so I've used that to test this round of fixes, this bug should be fixed for good now as I've re-factored the problem code to a more straightforward form. I've also fixed the CMake policy warnings.
Thanks for the log that was a big help. I noticed in the log that the cmake invocation is being passed: -DGRAPHITE2_NTRACING:bool=1 Whilst it works I believe that is a typo, and it should be: -DGRAPHITE2_NTRACING:BOOL=ON Regards, Tim On Fri, Dec 18, 2015 at 3:29 AM, Rene Engelhard <r...@debian.org> wrote: > forwarded 805323 Tim Eves <tim_e...@sil.org> > thanks > > Hi Tim, > > On Thu, Dec 17, 2015 at 11:37:20AM +0700, Tim Eves wrote: > > The bug has been fixed in commit > 594d92c0c0efbd3a87a32260f57e502200c351a7 > > "Fix misaligned access on ARM and HP PA processors during collision". > > > > It was a non-32 bit aligned 32bit read, some processors (ARM) are > stricter > > about this than others (Intel), which could explain the fact it built > fine > > on other BE archs. > > Unfortunately the patch doesn't work for me, I still get a build failure > on armhf. > (See attached buildlog). gdb'ing core gives > > (cowbuilder-unstable)rene@raspberrypi:~/tmp/graphite2-1.3.4/build/tests$ > gdb --core=core > GNU gdb (Debian 7.10-1) 7.10 > Copyright (C) 2015 Free Software Foundation, Inc. > License GPLv3+: GNU GPL version 3 or later < > http://gnu.org/licenses/gpl.html> > This is free software: you are free to change and redistribute it. > There is NO WARRANTY, to the extent permitted by law.
