yes, please do not close this bug as i can reproduce it even with
-fno-strict-aliasing, but it seems it breaks at least in four files
(dfgparser.c, list.c, sharing.c, subst.c) so it could take some time to reduce.
I'd like to see your backtrace of segfault to compare with.
(compile it with -O2 -g, and do gdb --args ./a.out bug_trigger and then 'run'
and 'bt')
