            Bug ID: 241439
           Summary: csu dynamiclib/init_test:jcr_test does not pass on
                    armv7
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: kevans at freebsd.org

We currently hit the following failure:

dynamiclib/init_test:jcr_test  ->  failed: 
 /usr/src/lib/csu/tests/init_test.c:82: Incorrect pointer passed to
_Jv_RegisterClasses  [0.029s]

This test is comparing jcr_ptr to jcr_func_ptr; the former being what's passed
to _Jv_RegisterClasses. If I dump them in the ATF_REQUIRE_MSG, jcr_ptr == 12000
and jcr_func_ptr == 20057000; jcr_ptr == 12000 corresponds to this:

$ readelf -a init_test | grep '\.jcr'
...
  [17] .jcr              PROGBITS        00012000 002000 000000 00  WA  0   0 
4

The value of jcr_func_ptr is consistent here:

(gdb) print jcr_func_ptr
$3 = (const void *) 0x20057000
(gdb) print &jcr_func
$4 = (func_ptr *) 0x20057000

For completeness:

$ readelf -a libh_csu.so | grep '\.jcr'
...
  [16] .jcr              PROGBITS        00002000 002000 000004 00  WA  0   0
