--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed.  The warning is the result of splitting -Wformat-truncation out of
the -Wformat-length warning in r244210.  Based on the note ("format output
between 22 and 32 bytes") 32 sounds like the right size.  Let me do a build
with BOOT_CFLAGS='-O0' to see if there are  any other problems and fix them
all.
