            Bug ID: 62164
           Summary: 5.0: ICE: error: Both section and comdat group is set
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: adam at os dot inf.tu-dresden.de

The following code causes an ICE:

class T { static void t(); };

class U
{
public:
  static void u() __attribute__ ((__section__ (".initcall.text")));
};

inline void U::u() {}

void T::t() { U::u(); }

$ g++ --version
g++ (GCC) 5.0.0 20140817 (experimental)
$ g++ -c t.c

Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.

The problem seems to be that U::u() is tagged inline. If it is not inline,
there is no ICE.
No ICE for <= 4.9.
