            Bug ID: 105074
           Summary: [12 Regression] -fanalyzer ICEs on gnutls-3.7.3:
                    cgraph_node::get_edge(gimple*) SIGSEGV
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: analyzer
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---

Initially observed ICE when built gnutls-3.7.3 on this week's gcc. Here is the
minimal reproducer:

$ cat cert-session.c
// gcc-12.0.0 -O2 -fanalyzer -o a.o  cert-session.c
void _gnutls_log(const char *);
static void _gnutls_ocsp_verify_mandatory_stapling(void) {
  _gnutls_log(__func__);
}
void check_ocsp_response_gnutls_x509_cert_verify_peers(void) {
  _gnutls_ocsp_verify_mandatory_stapling();
}

$ /tmp/gb/gcc/xgcc -B/tmp/gb/gcc -O2 -fanalyzer -c cert-session.c
during IPA pass: analyzer
In function ‘_gnutls_ocsp_verify_mandatory_stapling’,
    inlined from ‘check_ocsp_response_gnutls_x509_cert_verify_peers’ at
cert-session.c:7:3:
