[cfe-dev] CodeGenTypes.cpp assertion raised

[Michael Zolda]

Hi!


One more:

struct s *x = 0;

struct s {
  char c;
  struct s *n;
};

void foo(struct s* t, char y) {
  t->c = y;
}


Causes:

There's still more to come...

We would like to use clang in our research project, but we are still
having some troubles compiling our benchmark sources. We appreciate your
work on clang and hope that we can contribute to improving clang by pointing
out some problems. We value your support!



Cheers,
Michael
