the ternary operator causes incrementation of left hand side expression to occurs before it should in an expression where the variable appears at both side of the affectation expression.
example: *s++ = (*s == 'x') ? 'X': *s;
Note: this does not appears in gcc-2.96 (Mandrake 8.2)
gcc 2.95.2 - gcc 2.95.3 - gcc 3.04
gcc 2.95.3, gcc 3.04 (home compiled on Linux Mandrake 8.1)
Mac OS X : gcc 2.95.2
#define STRING "abc"
char s, *t;
t = s;
while (*t != '\0')
*t++ = (*t == 'b') ? 'X': *t;
/* this print "Xc" instead of "aXc" */
Must replace ternary operator by if/else instruction
State-Changed-Why: Not a bug. The standard states that whether the LHS or the RHS of '=' is evaluated first is undefined. You were lucky before.
