 Hi Dave,
 
 I have found that crash-4.0.9 cannot load any extensions on 32-bit hosts, even 
 echo.so. Running crash with -d5 on a live 32-bit kernel I can see that it 
 fails as
 
 crash> extend extensions/echo.so
 extend: ./extensions/echo.so: machine type mismatch: 3
 extend: ./extensions/echo.so: not an ELF format object file
 
         if (!is_shared_object(ext->filename)) {
                 error(INFO, "%s: not an ELF format object file\n",
 
 
 Something is wrong in is_shared_object() logic on IA32. It is interesting that 
 there are no problems with crash-4.0.9 and extensions on 64-bit systems. As 
 most of us are running 64 bits, this probably explains why nobody reported 
 this bug yet. 
Thanks -- I'll take a look.  It appears that the extension module
is passing this test in is_shared_object(): 
  if (elf64->e_ident[EI_CLASS] == ELFCLASS64 ...
What does "readelf -a" show for the echo.so file?  (I don't have
a handy x86 machine readily available at the moment...)
