That's what happens to mail sent to me personally :(. I'm assuming it's ok forward this output to the list. Is it correct that the statically linked version (notmuch) worked OK but the dynamically linked version (notmuch-shared) failed? That's consistent with what I observe on Debian, it's just that here the dynamically linked version falls back on the canonicalize_file_name in glibc, hiding the error. For people on glibc platforms who want to play with this, set HAVE_CANONICALIZE_FILE_NAME=0 in Makefile.config, make clean, make % nm notmuch-shared | grep canonicalize d
