Wt

Hi,

I have a crash of Wt with the stacktrace pointing to renderfv() method.

The problem is in renderfv() using generic_double_to_str() in some cases, as it lets write sprintf without limitation in length to a char * buf of fixed size (for example char * buf[30]):

static inline char *generic_double_to_str(double d, char *buf)

{

if (boost::math::isnan(d)) {

if (boost::math::isinf(d)) {

sprintf(buf, "%f", (float)d);

Suggested solution: pass on the digits parameter to this function and set the format accordingly.

Best,

Tassilo
