This works fine: ...

Interesting.  It doesn't work here (on Linux, though), independently of whether I declare/pass arguments to main or not: 

#!/usr/bin/perl

use Inline 'C';
main();
__END__
__C__
int main()
{
  printf("foo\n");
  return 0;
}

$ ./826910.pl
Segmentation fault

My guess would be that this is because main is special (the entry point of an executable).  If you rename the XS routine to something else like main2, however, it prints "foo" as expected.
