Thanks for the report.

This time I'm unable to reproduce it locally.
I'm using latest sed from git ( v4.5-27-g36e3485 ),
with gnulib version c5e76a9560 ( v0.1-2015-gc5e76a956 ),
compiled with gcc-8.2 and gcc-6.3.
I tried with both ASAN and valgrind, and they don't report
a SEGV.

May I ask for more details? which git version are you using,
did you re-run "./bootstrap", which compiler, etc?

Thanks!
