Bug ID: 99771
Summary: Analyzer diagnostics should not say "<unknown>"
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
Target Milestone: ---
Various analyzer diagnostics talk about "<unknown>"; examples can be seen in
the testsuite:
data-model-10.c:
*new_table->m_f = NULL; // "dereference of possibly-NULL '<unknown>'"
malloc-1.c (test_44):
free (global_ptr); // "leak of '<unknown>'"
malloc-ipa-13.c:
calls_free (f.m_p); //"passing freed pointer '<unknown>' in call to
'calls_free' from 'test'"
and IIRC I've seen these "in the wild" recently as well.
We shouldn't emit "<unknown>" to the end-user.
Filing this bug to have a place to track fixing these.
