Hi all,

After merging the tip-fixes tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from builtin-check.c:16:
In function 'save_argv',
inlined from 'objtool_run' at builtin-check.c:296:2:
tools/objtool/include/objtool/warn.h:47:17: error: '%s' directive argument is null [-Werror=format-overflow=]
47 | "%s%s%s: objtool: " format "\n", \
| ^~~~~~~~~~~~~~~~~~~
tools/objtool/include/objtool/warn.h:92:9: note: in expansion of macro 'WARN'
92 | WARN("%s: " format " failed: %s", __func__, ##__VA_ARGS__, strerror(errno))
| ^~~~
builtin-check.c:241:25: note: in expansion of macro 'WARN_GLIBC'
241 | WARN_GLIBC("strdup(%s)", orig_argv[i]);
| ^~~~~~~~~~
cc1: all warnings being treated as errors

Caused (or exposed?) by commit

c5995abe1547 ("objtool: Improve error handling")

I have used the tip-fixes tree from next-20250325 for today.
