I ran into what looks like the same error when building but could not
reliably reproduce it. However, I *am* able to reproduce something
possibly related. Because I'm not sure, I replied to your original post
rather than down thread (so as not to cause an unnecessary ruckus).

Unfortunately, to run the test shown in the attached log you need a file
that's not in the Emacs tree. It can be generated with

1. $ mkdir test/lisp/erc/resources/fill/snapshots/.graphic

2. $ ERC_TESTS_SNAPSHOT_SAVE=erc-fill-wrap--merge-action \
     make -C test \
     TEST_INTERACTIVE=yes \
     SELECTOR=erc-fill-wrap--merge-action \
     lisp/erc/erc-fill-tests.log &&
     rm test/lisp/erc/erc-fill-tests.log &&
     stat test/lisp/erc/resources/fill/snapshots/.graphic/merge-wrap-01.eld

The current directory in the logged session is ./test, and the invoking
command appears on the first line of the log.

Thanks.
