            Bug ID: 105765
           Summary: [13 Regression] ICE: Segmentation fault (in
                    ana::region_model::deref_rvalue)
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: analyzer

  Target Milestone: ---

gcc 13.0.0 20220522 snapshot (g:a60228404f2ac11b5eb66270037ff3fa6bf948e5) ICEs
when compiling the following testcase, reduced from
clang/testsuite/CodeGen/ms_abi_aarch64.c from the clang 14.0.3 test suite, w/
-fanalyzer:

void
f4 (int a, ...)
{
  __builtin_ms_va_list ap, ap2;

  __builtin_ms_va_start (ap, a);
  __builtin_ms_va_copy (ap2, ap);
  __builtin_ms_va_end (ap);
}

% gcc-13.0.0 -fanalyzer -c jhszfd06.c
during IPA pass: analyzer
jhszfd06.c: In function 'f4':
jhszfd06.c:7:3: internal compiler error: Segmentation fault
    7 |   __builtin_ms_va_copy (ap2, ap);
