When looking for ABI mis-matches (a common cause of seg-faults) the objdump, readelf and nm utilities are a better source of information.

Information such as:
Code:
core2quad hello $ readelf -a hello | less

ELF Header:

  Entry point address:               0x838c
  Start of program headers:          52 (bytes into file)
  Start of section headers:          2112 (bytes into file)
  Flags:                             0x5000002, has entry point, Version5 EABI
  Size of this header:               52 (bytes)
  Size of program headers:           32 (bytes)
  Number of program headers:         8

Dynamic section at offset 0x56c contains 25 entries:
