The test fails due to:

./gnulib-tests/test-canonicalize-lgpl
test-canonicalize-lgpl.c:74:14: runtime error: null pointer passed as argument 1, which is declared to never be null
    #0 0x40169c in main (/home/marxin/Programming/sed/gnulib-tests/test-canonicalize-lgpl+0x40169c)
    #1 0x7f76821e8e0a in __libc_start_main ../csu/libc-start.c:308
    #2 0x4011f9 in _start (/home/marxin/Programming/sed/gnulib-tests/test-canonicalize-lgpl+0x4011f9

-fsanitize=undefined is used. Problem is that the function has nonnull(1) attribute.

One another issue I see with UBSAN:

$ cat testsuite/debug.log
...
debug.pl: test c10_: stderr mismatch, comparing c10_.3 (expected) and c10_.E (actual)
*** c10_.3	Tue Nov 19 19:42:55 2019

[Message part 1 (text/plain, inline)]

I suspect this was related to the gnulib bug https://lists.gnu.org/archive/html/bug-gnulib/2020-01/msg00040.html
and fixed in https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=b7d7afe10ddf599452bd80b8a840c830cd474b09

This should be present in the latest sed releases. I can't reproduce it, so it was either that,
or a subsequent commit (of which there's been quite a few: https://git.savannah.gnu.org/cgit/gnulib.git/log/?qt=grep&q=canonic).
