Aspell memleak!?

Any advice on the following? After a few days of debugging, I've isolated
what appears to be an aspell meleak. The program below leaks 64 bytes per
spelling suggestion, or about a gigabyte in a few minutes. As far as I can
tell, the program is written in exactly the style that the documentation
calls for. Am I missing something?

This is on Debian stable, version 0.60.8-3

#include <malloc.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <aspell.h>

// Compile with
// cc aspell-memleak.c -laspell

int main()
{
	AspellConfig *config = new_aspell_config();

	aspell_config_replace(config, "lang", "en_US");

	AspellCanHaveError *spell_err = new_aspell_speller(config);
	AspellSpeller *speller = to_aspell_speller(spell_err);

	size_t k=0;
	char* word = "asdf";
	for (int l=0; l<1000000; l++)
	{
		/* Returns 1 is the word is in dict. */
		int found = aspell_speller_check(speller, word, -1);
		// printf("Found the word: %d\n", found);

		const AspellWordList *list = aspell_speller_suggest(speller, word, -1);
		AspellStringEnumeration *elem = aspell_word_list_elements(list);
		unsigned int size = aspell_word_list_size(list);

		const char *aword = NULL;
		while ((aword = aspell_string_enumeration_next(elem)) != NULL)
		{
			// printf("Spell suggesion: %s\n", aword);
			k++;
		}
		delete_aspell_string_enumeration(elem);

		if (0 == l%20000)
		{
			printf("Loop count= %d spell suggests= %lu\n", l, k);
			malloc_stats();
		}
	}

	delete_aspell_speller(speller);
	delete_aspell_config(config);
}
