Description of problem:

Hi. I'm observing that dwarf_aggregate_size() returns bogus results when looking at double-dimensional arrays. For instance, looking at

  double dd[3][5];

It says the aggregate is 64-bytes long instead of 120. The bug is that it ends up computing (3+5)*8 instead of 3*5*8.

I'm attaching a simple test case. It loads the current process's debug information, and prints out the size of dd, defined as above. It shows the failure:

  :/tmp$ gcc -g -ldw -lelf dwarf_aggregate_size_bug.c -o dwarf_aggregate_size_bug

  :/tmp$ ./dwarf_aggregate_size_bug                                              
  Found DIE for 'dd'. size: 64

Version : elfutils-0.168-8.el7
