indeed. Will investigate further. Thanks again for the bug report. This time you've found a 12-year old bug... Details are here: https://lists.gnu.org/r/bug-gnulib/2018-08/msg00142.html The fix is now in GNU libc: https://sourceware.org/git/?p=glibc.git;a=commit;h=bc680b336971305cb39896b30d72dc7101b62242 and in gnulib: https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=53e2c179f26a890fa6685af4b6c1397ee370433b Next time we pull gnulib updates into sed this will be fixed in sed as well. regards, - assaf
