Seeing this on big endian with -m32.  Works fine on BE with -m64.

Seen on all 32-bit targets actually (at least Solaris/SPARC, Solaris/x86, and
32-bit Linux/x86_64).

The referenced patch added the test that is failing.  How is that a regression?
 Or are you suggesting that the test works without the rest of the patch
applied?

/* { dg-warning {cast to pointer from integer of different size} "" { target
*-*-* } .-2 } */

I'm guessing it's this that's causing the problem because int and int* are the
same size on 32-bit targets.  So would changing the test to:

-  int arr[20];
+  char arr[20];

be enough?  AFAIK we don't have any targets with 8-bit pointers.

Test passes with the attached change on hppa-unknown-linux-gnu.

    gomp: testsuite: improve compatibility of bad-array-section-3.c [PR113428]

    This test generates different warnings on ilp32 targets because the size
    of an integer matches the size of a pointer.  Avoid this by using
    signed char.

    gcc/testsuite:

            PR testsuite/113428
            * gcc.dg/gomp/bad-array-section-c-3.c: Use signed char instead
            of int.
