It still doesn't crash here.

> 0x84ad6c0:2688 bad alloc_header block free() @ /tmp/buildd/elinks-0.13~20080907/src/document/document.c:141, alloc'd at /tmp/buildd/elinks-0.13~20080907/src/document/html/renderer.c:168

done_document() in src/document/document.c:

140		for (pos = 0; pos < document->height; pos++)
141*			mem_free_if(document->data[pos].chars);

realloc_line() in src/document/html/renderer.c:

156	struct line *line;
168*	if (!ALIGN_LINE(&line->chars, line->length, length + 1))
169		return -1;

src/document/document.h:

32	struct line {
33		struct screen_char *chars;
34		int length;
35	};

So alloc_header.magic of line.chars has somehow become corrupted.
However, it's perhaps not a simple underflow, because
alloc_header.file seems correct.  It might be an overflow of the
previous block, or a write via a stale pointer.

What do you have in /etc/elinks/elinks.conf?

What is the processor architecture? (e.g. i686 or amd64 or alpha)
If it's i686, I could perhaps examine a core dump.
(Please don't send core dumps to elinks-dev.)

What are $TERM, $LANG, $LC_CTYPE, $LC_ALL?

Again, if you can reproduce the crash under valgrind, that will
be most helpful.  Alternatively, you might try electric-fence if
you have lots of memory.  Disabling --with-guile and other
scripting modules may speed up tests and reduce memory
consumption and irrelevant error reports from valgrind.
