I'm no XS expert (I prefer Inline::C) but SIGSEGV leads me to believe you're blowing the stack. PUSHs will not automatically expand the stack for you. Try XPUSHs instead. Just out of curiosity, does the dir you're SIGSEGV'ing on have many more entries than the dirs it works okay on?

update: I couldn't resist a little Inline::C rewrite:

#!/usr/local/bin/perl -w

use Inline C;
use strict;

foreach( @ARGV ) {
        my( @stuff ) = readdir_inode($_);

        foreach(@stuff) {
                foreach( @$_ ) {
                        print $_, " ";
                }
                print "\n";
        }
}

__END__
__C__
#include <sys/types.h>
#include <dirent.h>
#include <stdio.h>

void readdir_inode ( char *dirname ) {
        struct dirent *ent;
        DIR *dir;
        SV *record[2];
        AV *entry, *ret_val;

        Inline_Stack_Vars;
        Inline_Stack_Reset;

        dir = opendir(dirname);
        if( dir ) {
                while( ent=readdir(dir) ) {
                        record[0] = newSVpv(ent->d_name, 0 );
                        record[1] = newSViv((IV)ent->d_ino);
                        Inline_Stack_Push(newRV_noinc((SV*)av_make(2,r
+ecord)));
                }
                closedir(dir);
        }

        Inline_Stack_Done;
}
