dSprintf problem

So I was trying to do polygon collisions. I get an error that I am trying to put to much information in my buffer. But I am not setting any information. Infact I used the default toast and got the same problem with that just by switching the shape to a polygon instead of circle. This is where my error is.

int dSprintf(char *buffer, dsize_t bufferSize, const char *format, ...)
{
va_list args;
va_start(args, format);
S32 len = vsprintf(buffer, format, args);

// Sanity!
AssertFatal(len <= bufferSize, "dSprintf - String format exceeded buffer size. This will cause corruption.");

return (len);
}

Sometimes it gives me long lines like this. But when I run the program from the compiler it gives me much smaller numbers. What's the deal? Why am I getting an error because my len is to large??

0 0 0.0000 -1.0000 15.2690 -19.5025 64.0000 -12.8000 14.4800 -19.5025 3823037724445304499356824878417182720.0000 382303138619230

and

0 0 0.0000 -1.0000 15.8125 -19.5025 64.0000 0.0000 14.4800 -19.5025 221831645277151347207202048441319424.0000 221831249136338775885514080721567744.0000

And when compiled and ran from compiler:

0 0 1.0000 0.0000 40.5025 -49.4079 64.0000 -12.8000 40.5025 -51.4079 0.0000 0.0000
