Re: [Dillo-dev] dillo-0.8.6-rc2: bug in Html_parse_entity

28 Mar 2006

      Hi Jorge,

I have found the following small problem in html.c:

the comparison of HTML versions in Html_parse_entity does not work,
apparently because of floating point roundoff errors: On my machine
(i386, Debian Sarge, libc6), the comparison (lines 1016ff)

         if ((html->DocType == DT_HTML && html->DocTypeVersion == 4.01) ||
             html->DocType == DT_XHTML)
            MSG_HTML("undefined character entity '%s'\n", tok);

is never triggered for HTML 4.01. In fact, html->DocTypeVersion - 4.01
has the value 2.288818e-07. Currently this is the only place where such
a comparison is used, but I guess this might change in future.

Al the best,
