Properties UDF error
 

Below is my code
"#include "udf.h"
DEFINE_PROPERTY(water_density,cell,thread)
{
double rho,temp1;
temp1 = C_T(cell, thread);
rho = 1000*0.3471*pow(0.2741,(-1+(temp1/647.13)*0.28571));
return rho;

}

temp1 = C_T(cell, thread);

return k;

{

"



but when i interpret my code i received error
"received a fatal signal (segmentation fault)"

Thanks in advance
