Compiler Bug?

[bgpartri]

Is there some reason this code should hang? Am I missing something?

#include <18f452.h>
#include <math.h>

void main(void){
float number_log;
number_log = log(2.0);
number_log += 1;
}

I just put the second executable statement in there so I could single step somewhere. It turns out it isn't needed, because it never returns from the log function.

The second include was supposed to be <math.h>.

Since my first post, I have found that exp doesn't work either.

Very interesting. I guess <-m-a-t-h-.-h-> gets processed by something along the way to the list.

You should add a while(1) to keep the processor from going to sleep.

Thanks. I don't think I would ever have figured that out.

I was still stumped for a while about why my real program still didn't work. I was not programming enough memory. For whatever reason, MPLAB didn't give me an error. It was falling off the end of the program in some way. That program did have a while(TRUE); at the end.

Anyway, its fixed now.
