Description of problem:
Hi. I'm observing that dwarf_aggregate_size() returns bogus results when looking at double-dimensional arrays. For instance, looking at
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
Found DIE for 'dd'. size: 64
Version : elfutils-0.168-8.el7
