--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
I can't reproduce the failures with my cross-compilers.
For instance, with an arm-none-linux-gnueabihf cross I get the expected output
for a test case reduced from the one on line 120:
$ cat u.c && /build/arm-none-linux-gnueabihf/gcc-svn/gcc/xgcc -B
/build/arm-none-linux-gnueabihf/gcc-svn/gcc -O2 -S -Wall -Wno-format
-Wformat-overflow -fexec-charset=IBM1047 u.c
void f (char *d)
{
__builtin_sprintf (d, "%9223372036854775808i", 0);
}
u.c: In function ‘f’:
u.c:3:24: warning: ‘%9223372036854775808i’ directive width out of range
[-Wformat-overflow=]
3 | __builtin_sprintf (d, "%9223372036854775808i", 0);
| ^~~~~~~~~~~~~~~~~~~~~~~
