[Bug 2056751] Re: Error compiling with glibc2.35 in Ubuntu22.04.3 LTS

[Simon Chopin]

To be more precise: I can't reproduce it using gcc or clang, no matter
the fortify level, and the upstream fix
https://sourceware.org/git/?p=glibc.git;a=commit;h=5a5f94af0542f9a35aaa7992c18eb4e2403a29b9
mentions that you can only trigger it on older releases that aren't
available in Jammy.

As a policy we don't backport fixes without a proper test plan.

Title:
  Error compiling with glibc2.35 in Ubuntu22.04.3 LTS

Status in glibc package in Ubuntu:
  Incomplete

Bug description:
  When compiling code on Ubuntu 22.04.3 LTS, a glibc2.35 error message
  appears as follows:

  /usr/include/x86_64-linux-gnu/bits/string_fortified.h:110: error:
  macro "__fortified_attr_access" requires 3 arguments, but only 1 given

  The cause is an error with __fortified_attr_access at line 110 in
  string_fortified.h, which should be modified to:

  > @@ -107,7 +107,7 @@ __NTH (stpncpy (char *__dest, const char *__src, size_t __n))
  >   # else
  >   extern char *__stpncpy_chk (char *__dest, const char *__src, size_t __n,
  >                               size_t __destlen) __THROW
  > -  __fortified_attr_access ((__write_only__, 1, 3))
  > +  __fortified_attr_access (__write_only__, 1, 3)
  >     __attr_access ((__read_only__, 2));
  >   extern char *__REDIRECT_NTH (__stpncpy_alias, (char *__dest, const char *__src,
  >                                                  size_t __n), stpncpy);

  It has been noted that this error has been corrected in newer versions
  of glibc. It is recommended to update to the latest version of glibc.
