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.

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