            Bug ID: 77840
           Summary: List-initialization and copy-constructor
           Product: gcc
           Version: 6.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

Hi,
I would like to post a bug report for the GNU C/C++ compiler 6.1.1.
We use the compiler to generate code for a PowerPC processor.
Invokation line for the GNU C compiler:

ccppc -c -x c -std=gnu11 -Wall -Werror -g -mcpu=e6500 -m32
      -maltivec -mvrsave -ftls-model=local-exec -msdata=sysv
      -fno-common -fno-openmp -mbig -mmultiple -mno-string -misel
      -mstrict-align -fverbose-asm -G 8 -O3
      -I<some include paths>
      -D<some #define's>
      X.C -oX.O


// file X.C

struct X
{
    X (int);
    X (const X&) = delete;
};

X arrX = { 1, 2, 3 };


The compiler rejects this program because the copy constructor is
deleted. But according to the C++11 standard this initialization
should not involve a copy/move constructor (cf. 12.6.1/2).

By the way, the compiler accepts a slighty different programm:

// file X.C

struct X
{
    X (int);
    X (const X&) = delete;
};


X arrX[] = { {1}, {2}, {3} };



With kind regards
W. Roehrl
