On AIX 7.1 and 7.3.1, I see this test failure: FAIL: test-realloc-posix ========================
../../gltests/test-realloc-posix.c:34: assertion 'p != NULL' failed FAIL test-realloc-posix (exit status: 134) The cause is my change from 2024-10-27: <https://lists.gnu.org/archive/html/bug-gnulib/2024-10/msg00238.html> where I moved the unit test, but without ensuring that the realloc() function actually satisfies this unit test. Paul's change from 2024-10-30 <https://lists.gnu.org/archive/html/bug-gnulib/2024-10/msg00252.html> then was half of what's needed to make the 'realloc-posix' module behave like we want. Here's the second half of the fix: 2024-11-01 Bruno Haible <br...@clisp.org> realloc-posix: Fix test failure on AIX (regression 2024-10-27). * m4/realloc.m4 (gl_FUNC_REALLOC_0_NONNULL): New macro. * modules/realloc-posix (configure.ac): Invoke it. diff --git a/m4/realloc.m4 b/m4/realloc.m4 index 4f414b4817..639d7a9efe 100644 --- a/m4/realloc.m4 +++ b/m4/realloc.m4 @@ -1,5 +1,5 @@ # realloc.m4 -# serial 36 +# serial 37 dnl Copyright (C) 2007, 2009-2024 Free Software Foundation, Inc. dnl This file is free software; the Free Software Foundation dnl gives unlimited permission to copy and/or distribute it, @@ -75,3 +75,14 @@ AC_DEFUN([gl_FUNC_REALLOC_POSIX] fi fi ]) + +# gl_FUNC_REALLOC_0_NONNULL +# ------------------------- +# Replace realloc if it is not compatible with GNU libc. +AC_DEFUN([gl_FUNC_REALLOC_0_NONNULL], +[ + AC_REQUIRE([gl_STDLIB_H_DEFAULTS]) + + _AC_FUNC_REALLOC_IF([], [REPLACE_REALLOC_FOR_REALLOC_POSIX=1], + ["$gl_cross_guess_normal"]) +]) diff --git a/modules/realloc-posix b/modules/realloc-posix index 566d389194..e7188b5f04 100644 --- a/modules/realloc-posix +++ b/modules/realloc-posix @@ -12,6 +12,7 @@ stdlib configure.ac: gl_FUNC_REALLOC_POSIX +gl_FUNC_REALLOC_0_NONNULL if test $REPLACE_REALLOC_FOR_REALLOC_POSIX = 1; then AC_LIBOBJ([realloc]) fi
