Problem With Null Pointer Test And 2 Other Conditions

Recommended Posts

Hi Dave,


SourceBoost V7.01



I'm not sure whether it is valid to assume that conditions are evaluated in the order they are written with SourceBoost but either way the code below generates a compiler error.



#include <system.h>


typedef struct {

unsigned char a;

} TTestStruct;


typedef TTestStruct* PTestStruct;


TTestStruct s1;

PTestStruct ps;


void main(void)


ps = &s1;


//Removing any one of the 3 conditions allows it to compile

while (

(ps) && //Error: Failed to generate expression

(ps->a >= 1) &&

(ps->a <= 10)
