[xml] strace reports SIGFPE during parsing

["Petr Kozelka" <pkozelka centrum cz>]

Hello,

as I started to test the recently announced libxml2 for pas, I 
discovered that whenever I try to parse an XML file, for instance 
with xmlParseFile function, a SIGFPE occurs.
The version I use is 2.4.0.
I tested the same with version 2.3.9 and no SIGFPE is there.
This supersimple program was used to test it 
(just a call to xmlParseFile):
---------------------t1.c--------------------
#include <libxml/parser.h>
 
int main(int argc, char** argv)
{
        xmlDocPtr doc = xmlParseFile(BAD_CAST argv[1]);
        return 0;
}
--------------------- end ------------------

when run with strace, it shows that SIGFPE occurs many times and 
is ignored (see log at the end of this message).
This is not a problem inside a normal C program, but Kylix seems 
to handle this signal in a way that terminates the application.
I do not want to override the signal handling in order to use 
libxml2 under Kylix.

Does anybody know where this strange behavior comes from ?

Thanks,
Petr
