--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> ---
So it's equivalent to:
$ cat ~/Programming/testcases/pr84592-3.c
#include <stdio.h>
int
main (void)
{
int n[1];
n[0] = 4;
#pragma omp target
{
static const int test[] = {1,2,3,4};
n[1] += test[n[0]];
}
printf ("n: %d\n", n[0]);
return 0;
}
$ /tmp/install/usr/local/bin/x86_64-pc-linux-gnu-gcc
~/Programming/testcases/pr84592-3.c -fopenmp
setting in_other_partition: test.2531: 1
test: 1

It's logically not supported as I guess you have 2 versions of the pragma body
and thus 2 variables are expected. Proper fix would be to disable the pass in
case of an offloading is used.
And it's questionable whether an error should be printed for the test-case
above.
