You probably need to adjust that command line to match the way you're building Emacs. My output with current master on Fedora x86-64 is: > "GCALIGNED_STRUCT" __attribute__ ((aligned (8))) > However, in thinking about this some more I do see a problem that could explain your symptoms, a problem that resulted from a merge from emacs-26 that collided with changes in the master without Git (or > me) noticing the collision. I installed the attached patch into master to fix it. Please try this patch first, and we can worry about GCALIGNED_STRUCT only if this patch does not fix things for you. Hi Paul, That works. http://pkg.awarnach.mathstat.dal.ca/data/11i386-default/2018-10-19_14h24m35s/logs/emacs-devel-27.0.50.20181018,2.log The FreeBSD emacs-devel package is updated, so this can get wider testing. https://svnweb.freebsd.org/ports?view=revision&revision=482447 Thank you. -- Joseph
