My patch and Ilya's option are not mutually exclusive.
The loop used in the original code can still possibly
break, with or without
"-fno-aggressive-loop-optimizations", because, as I
mentioned, the C standard doesn't guarantee there will
be no paddings between the struct's fields (C 2011
(N1570) 6.7.2.1 15, “There may be unnamed padding within
a structure object, but not at its beginning.”).
The flag fixes it for gcc 4.8, that's all.
And the mentionned patch is:
https://bugzilla.redhat.com/attachment.cgi?id=800563&action=diff&context=patch&collapsed=&headers=1&format=raw
Olivier submitted that patch upstream, but Sofia is not exactly
maintained at the moment.
