I have this c code, where i need to calculate a dobule from a long.

double result;
long t2_value;

t2_value = 72;
result = t2_value * 1.2;

Now this code crashes at "result = t2_value * 1.2;" only with the error "Vector 0000000006".

Here is the strange thing, if i replace

result = t2_value * 1.2;

with

result = 72 * 1.2;

evything works just as it should, i have tryed type casting t2_value as an double

result = ((double)t2_value * 1.2);

or making it an int istead of a long, but nothing helps.
