--- Comment #14 from Mikhail Maltsev <miyuki at gcc dot gnu.org> ---
Another reproducer:

$ cat genmodes.cc 
inline char *strchr(const char *, int) __asm("strchr");
inline char *strchr(const char *, int)
{
  return __builtin_strchr(0, 0);
}

int make_complex_modes()
{
  if (strchr(0, 0))
    return 1;
}

$ cc1plus -O -flto genmodes.cc -quiet -o - | as -o genmodes.o
$ lto1 genmodes.o -g -o /dev/null -quiet
genmodes.cc: In function 'make_complex_modes':
