            Bug ID: 107029
           Summary: ice during GIMPLE pass: reassoc
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

This C++ code:

class ImplicitBool ImplicitBool::*Reset___trans_tmp_1;
int ImplicitBool::*Reset___trans_tmp_2;
struct Chips {
  struct Clocks {
    void Reset(bool, bool);
    int next;
  };
  void Reset();
  Clocks clocks;
};
void Chips::Clocks::Reset(bool mmc5Chip, bool fdsChip) {
  next = mmc5Chip || fdsChip;
}
void Chips::Reset() { clocks.Reset(Reset___trans_tmp_1, Reset___trans_tmp_2); }

when compiled as follows by recent g++

$ ../results/bin/g++ -c -w -O2 -std=c++98 bug849.cc

does this:

bug849.cc: In member function ‘void Chips::Reset()’:
bug849.cc:14:6: error: invalid types for ‘bit_and_expr’
   14 | void Chips::Reset() { clocks.Reset(Reset___trans_tmp_1,
Reset___trans_tmp_2); }
      |      ^~~~~
