            Bug ID: 111092
           Summary: ice expand_fn_using_insn, at internal-fn.cc:214
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

For this C code:

typedef struct {
  long r;
  long c
} bool_mat_struct;
bool_mat_struct bool_mat_randtest_diagonal_mat;
bool_mat_randtest_diagonal_n;
bool_mat_randtest_diagonal() {
  bool_mat_randtest_diagonal_n =
      bool_mat_randtest_diagonal_mat.r > bool_mat_randtest_diagonal_mat.c
          ? bool_mat_randtest_diagonal_mat.c
          : bool_mat_randtest_diagonal_mat.r;
}

compiled by recent gcc and compiler flags -O3 -march=znver2, does this:

$ /home/dcb38/gcc/results.20230817.asan.ubsan/bin/gcc -c -w -O3 -march=znver2 
bug948B.c
$ /home/dcb38/gcc/results.20230818.asan.ubsan/bin/gcc -c -w -O3 -march=znver2

during RTL pass: expand
bug948B.c: In function ‘bool_mat_randtest_diagonal’:
