could be reproduced only if we have structure variables named the same in different frames there is a consequence for simple types:
void foo() {
int x = 5;
x++;
x--;
}
int main(int argc, char**argv) {
int x = 2;
foo();
return 0;
}
here if we change value of x inside foo it will be changed in main
This is a showstopper as a debugger breaks the expected way of execution. Does this bug has the same root cause as #196846 ? no, they are different fixed in trunk: http://hg.netbeans.org/cnd-main/rev/1333130a00c1 Vladimir, please review Fix reviewed. If there are no performance penalties, I'm fine with it. verified in dev build #5040 integrated into release70: http://hg.netbeans.org/releases/rev/115b91ffb1a3 Integrated into 'main-golden', will be available in build *201103290400* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main/rev/1333130a00c1 User: Egor Ushakov <gorrus@netbeans.org> Log: fixed #197053 (Changed variable value is set to variable with the same name in another frame) Verified in RC2 build 20110331 |
Code: struct A { int b; }; void foo() { A a; a.b = 17; a.b = 18; } int main(int argc, char**argv) { A a; a.b = 1; foo(); return 0; } Steps to reproduce: - step into - expand a value so that b is visible - do a step a.b value will become 1 - do step into foo a.b value remains 1 - do another step (a.b = 17;) a.b value still remains 1
