            Bug ID: 59565
           Summary: ICE on valid code in DWARF generation
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: drepper.fsp+rhbz at gmail dot com

I see an ICE with both 4.8.2 and the trunk version on the following code when
compiled like this:

  g++ -std=gnu++1y -c bug.cc -g

The backtrace is seen below.  The code is simple:

================================================================
extern double f1(double);
struct s1
{
  double v;
};
inline auto f1(const s1& p) { return s1 { f1(p.v) }; }
struct s2
{
  double v;
  auto operator-(const s2& r) const { return s2 { v - r.v }; }
};
struct s3
{
  double v;
  s1 operator/(const s3& r) const { return s1 { v / r.v }; }
};
void f2(s3 p1, s3 p2) { auto d1 = f1(p1 / p2); }
================================================================

Notice that s2 is actually not used yet remove the definition or just the
inline function and it works.

Jason,

I saw your commit to bug #53756 and thought about this bug.  I built the
current trunk version and the bug is now fixed.

Should this bug be closed as duplicate of 53756 or something else?

It got fixed by the r207197 commit, so let's dup it.
