Bug 503052 – sys-devel/gcc-4.7.3-r1 - ?

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description ewan.willis 2014-02-28 14:37:22 UTC]

The following (invalid) source produces an internal error

class FooBase
{
public:
  virtual bool isFoo() const = 0;
};

class Bar
{
public:
  void addControl(const FooBase& foo)
  {
    mFoos.push_back(foo);
  }

private:
  std::vector<FooBase> mFoos;

};

Attemping to compile on g++4.7.3-r1 produces the following message:
Internal compiler error: Error reporting routines re-entered.
Please submit a full bug report,
with preprocessed source if appropriate.

Please post your `emerge --info =sys-devel/gcc' output in a comment.

That doesn't even parse. Could you give a complete, valid example, please?

[Comment 3 ewan.willis 2014-02-28 16:13:18 UTC]

The sys-devel/gcc field from emerge --info is included in my first comment.

Appart from lacking '#include <vector>' in the original comment the source there invariably results in the problem described.

For clarity: 

#include <vector>

class FooBase
{
public:
  virtual bool isFoo() const = 0;
};

class Bar
{
public:
  void addControl(const FooBase& foo)
  {
    mFoos.push_back(foo);
  }

private:
  std::vector<FooBase> mFoos;

};

I hope this helps!
