Why dbx core dumps on input core file?

Question

Hi,
We have a Solaris 10 machine, on which dbx always core dumps when input any core files to it. What would possibly wrong with this machine? Or where should we look to find some clues?
Thanks a lot,
pam

Please create a perl script using the text below:
#!/usr/bin/perl
use File::Find;
sub wanted {
  return unless -x && -f;
  return unless /.*\.so\.[0-9]$/;
  return unless `/bin/file $_ | grep 64-bit`;
  $out = `elfdump -e $_ | grep e_shoff`;
  $out =~ m/e_shoff:\s+(0x[0-9a-f]+)\s/;
  if ($1 =~ m/[4c]$/) {
     print "bad alignment in file: $File::Find::name\n";
print "Looking for bad ELF section header table alignment in 64-bit files\n";
find(\&wanted, ( "/lib", "/usr/lib" ));Then, make it executable and run it (does not need root permissions):
any_user$  chmod +x check_library_alignment.pl
any_user$  ./check_library_alignment.pl
If the perl script reports mis-aligned libraries (elfsign modifies the alignment), this looks to be bug 6283299. If you are current on patches for Solaris as well as your SunStudio installation, you'll need to raise an SR requesting the fix. If you are not current on patches, you could start with SunStudio patches which was subsequently patched to address elfsign alignments.
