Bug#851903: gcc-4.9: gcc crashes with -mtune=native on RPi3
Package: gcc-4.9
Version: 4.9.2-10
Severity: normal
Dear Maintainer,
gcc 4.9.2-10 is core dumping if the command line contains -mtune=native. This is on the new RPi3 64 bit platform only as far as I can tell.
pi@emu:~/tmp $ cat hello.c
#include <stdio.h>
int
main(void)
{
printf("hello world\n");
return 0;
}
pi@emu:~/tmp $ gcc -o hello -mtune=native hello.c
