New Revision: 240208
URL: http://svn.freebsd.org/changeset/base/240208

Log:
  MFC r239962:
  
  Fix a twelve year old bug in readelf: when process_dynamic_segment()
  encounters a DT_RUNPATH entry, the global dynamic_info[] array is
  overrun, causing some other global variable to be overwritten.
  
  In my testcase, this was the section_headers variable, leading to
  segfaults or jemalloc assertions when it was freed later on.
  
  Thanks to Koop Mast for providing samples of a few "bad" .so files.
