It is well defined.
Anyway, most likely the bug is already during gimplification.
I see in the omplower dump:
int[0:(sizetype) D.2477] & c;
...

#pragma omp target private (c)
{
printf("t %p\n", &c);
}
return 0;

Works on x86_64/i686/ppc64/ppc64le/aarch64 for me, fails on armv7hfp, s390{,x}.
I'm not saying there is not a middle-end bug, will need to analyze it.

Does it work on other platforms?

--- Comment #1 from Jakub Jelinek ---
But the test is OpenMP 4.5, and OpenMP 4.5 does allow reference types in the
privatization clauses.
