Dear Xavier,

I have done changes in code for depth and topindex as follows.
Also I have commented callback registration for check_link and check_html for
narrow down the problem.

However, after doing this and analyzing crash dump it seems that there is some
issue with libhtrack with multi-threading.

Please find the attached crash dump analyzed using WinDbg.

Please revert back on this issue.

Thanks & regards,
Rajesh


	/* Create option settings and set callbacks (wrappers) */
	httrackp* opt = hts_create_opt();

	// Set crawl depth to 3
	opt->depth = 3;
	// Disable generation of top index
	opt->dir_topindex = 0;

	CHAIN_FUNCTION(opt, end, httrack_wrapper_end_431, NULL);	
//	CHAIN_FUNCTION(opt, check_link, httrack_wrapper_check_431, NULL);
//	CHAIN_FUNCTION(opt, check_html, httrack_wrapper_checkhtml_431, NULL);
	CHAIN_FUNCTION(opt, linkdetected, httrack_wrapper_linkdetected_431, NULL);

	/* Then, launch the mirror */
	int ret = hts_main2(argc, argv, opt);

	/* Clear option state */
	hts_free_opt(opt);
	hts_uninit();
