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.

type;
