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.
