| Summary | 0000666: Wrong evaluation of expression in the GUI |
| Description | When evaluating an expression in the GUI, the result "After statement" seems to be equal to the result "Before statement" in some cases (e.g. if the statement is a conditional). Of course, that is incorrect in the general cases.
|
| Steps To Reproduce | Consider the following program:
==========
int t[2], c;
void main(void) {
t[0] = 0;
t[1] = 0;
if (c) t[0] = 1; else t[0] = 2;
t[1] += t[0];
}
==========
1) Run the GUI with options -val -lib-entry on this program.
2) Left-click at the end of the line containing "if". The information panel indicates that this line modifies t[0]: good.
3) Right-click at the end of the line containing "if" and select "Evaluate expression".
4) Enter "t[0]" as expression.
5) the information panel indicates that t[0] is equal to 0 after this statement. Quite bad, doesn't it?
Note: before statement "t[1] += t[0]", t[0] is 1 or 2: that is ok and that is the expected result after the conditional...
