            Bug ID: 26962
           Summary: FAIL: gdb.base/solib-corrupted.exp: make solibs
                    looping
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: testsuite
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

On SLE-11, I see:
...
(gdb) PASS: gdb.base/solib-corrupted.exp: normal list
p/x _r_debug->r_map->l_next = _r_debug->r_map^M
'_r_debug' has unknown type; cast it to its declared type^M
(gdb) FAIL: gdb.base/solib-corrupted.exp: make solibs looping
...

So, we don't have glibc debug info, but we fail to detect this.

    [gdb/testsuite] Handle no glibc debuginfo in gdb.base/solib-corrupted.exp

    When running test-case gdb.base/solib-corrupted.exp on SLE-11, I get:
    ...
    (gdb) PASS: gdb.base/solib-corrupted.exp: normal list
    p/x _r_debug->r_map->l_next = _r_debug->r_map^M
    '_r_debug' has unknown type; cast it to its declared type^M
    (gdb) FAIL: gdb.base/solib-corrupted.exp: make solibs looping
    ...

    The reason that _r_debug has unknown type is that glibc debuginfo is not
    installed.  The test-case attempts to detect this but doesn't handle this
    particular error string.

    Fix this by adding the "unknown type" line to the regexp detecting missing
    glibc debuginfo.

    Tested on x86_64-linux.
