strange but only in release mode
this is my code:
#include <stdlib.h>
#include <stdio.h>
typedef struct
{
double d1,d2;
int iSize;
} P;
int filter(P *pP)
{
int j;
pP->d1=107;
pP->d2=61;
pP->iSize=3;
double dCond;
dCond=(pP->d1<pP->d2);
printf("dCond=%f\n",dCond);
if (pP->d1 < pP->d2)
{
pP->iSize--;
printf("inside if\n",j);
}
else
pP->iSize--;
return 0;
}
main()
{
P p;
filter(&p);
return 0;
}
in debug mode it is fine and the output is:
dCond=0.000000
but in release mode (when the optimization option under the C/C++ tab is 'maximize speed'). the output is strange (the if block is executed):
dCond=0.000000
inside if
could someone have an explaination to this ?
I'm running microsoft visual C++ 6.0 enterprise edition.
