Bug 470055

Description of problem:
For testing binutils, I have gathered a collection of various crashers, which I use for regression testing. As part of testing errata for rhel5.3, I ported this testsuite for elfutils, and few of the crashers do indeed crash various elfutils too. 

Version-Release number of selected component (if applicable):
elfutils-0.137-3.el5 (RHEL5.3) on all architecture

How reproducible:
always

Steps to Reproduce:
1. $ eu-nm ./corrupt_dwarf
Segmentation fault

2. $ eu-nm -D ./strings.072
Segmentation fault

3. $ eu-strip -o xxx ./try.out
