            Bug ID: 65364
           Summary: FAIL: gcc.dg/uninit-19.c  (test for warnings, line 22)
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: danglin at gcc dot gnu.org

On hppa64-hp-hpux11.11 and other PIC targets, the expected warning
does not occur at the expected line number.  I believe the test
was already adjusted once.

output is:

FAIL: gcc.dg/uninit-19.c (test for excess errors)
Excess errors:
/test/gnu/gcc/gcc/gcc/testsuite/gcc.dg/uninit-19.c:13:15: warning: 'n' may be
us
ed uninitialized in this function [-Wmaybe-uninitialized]

/* { dg-warning "may be used uninitialized" "" { target nonpic } 13 } */^M
/* { dg-warning "may be used uninitialized" "" { target { ! nonpic } } 22 }
*/^M

The hppa64-hp-hpux11.11 target is always PIC and the warning occurs at line 13.
