Bug ID: 88244
Summary: [libbacktrace] Failure to open .gnu_debuglink is
silent
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libbacktrace
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org

Test-case
Attached test-case exercises libbacktrace with a broken .gnu_debuglink:
...
$ ./etest
test1: [0]: missing file name or function name
FAIL: backtrace_full noinline
test2: [0]: missing file name or function name
FAIL: backtrace_full inline
test3: [0]: missing file name or function name
FAIL: backtrace_simple noinline
test4: [0]: missing file name or function name
FAIL: backtrace_simple inline
PASS: backtrace_syminfo variable
...
While the test-case is verbose about not finding specific debug info,
libbacktrace is silent about the underlying issue: failing to open
.gnu_debuglink.
