BUG: ESQL-C: Error "Division by Zero" During Precompilation

MORE INFORMATION

Other operators (such as +, -, and *) do not cause an exception error in NSQLPREP.

The following is a sample code fragment that will cause the ESQL-C precompiler to generate a division by zero exception:

int main (int argc, char** argv, char** envp)
{
int x;

EXEC SQL BEGIN DECLARE SECTION;

char o[3];

EXEC SQL END DECLARE SECTION;

x = 1;
x = 1 / x;   // causes div/0

return (0);
} /* end program */ 
				

The following sample code fragment will not cause the precompiler to generate an exception error because there is a character string variable assignment before the division expression:

int main (int argc, char** argv, char** envp)
{
int x;
char string[] = "";  // character string assignment
EXEC SQL BEGIN DECLARE SECTION;
char o[3];

EXEC SQL END DECLARE SECTION;
x = 1;
x = 1 / x;   // works now
return (0);
   } /* end program */
