--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
This seems to have been fixed as a result of introducing -Wformat-truncation in
r244210. Resolving as a duplicate of 77708.
For the record, here's the output at the default setting of the -Wformat-length
and -Wformat-truncation options with today's top of trunk:
$ (set -x; for o in 0 1 2; do gcc -O$o -S -Wformat -Wformat-length
-Wformat-truncation algapi.i; done)
+ for o in 0 1 2
+ /build/gcc-svn/gcc/xgcc -B /build/gcc-svn/gcc -O0 -S -Wformat -Wformat-length
-Wformat-truncation algapi.i
+ for o in 0 1 2
+ /build/gcc-svn/gcc/xgcc -B /build/gcc-svn/gcc -O1 -S -Wformat -Wformat-length
-Wformat-truncation algapi.i
+ for o in 0 1 2
+ /build/gcc-svn/gcc/xgcc -B /build/gcc-svn/gcc -O2 -S -Wformat -Wformat-length
-Wformat-truncation algapi.i
And here's the output at level 2:
$ (set -x; for o in 0 1 2 3; do gcc -O$o -S -Wformat -Wformat-length=2
-Wformat-truncation=2 algapi.i; done)
+ for o in 0 1 2 3
+ /build/gcc-svn/gcc/xgcc -B /build/gcc-svn/gcc -O0 -S -Wformat
-Wformat-length=2 -Wformat-truncation=2 algapi.i
