Error description
===== DESCRIPTION: The following test case produces an incorrect result when -O2 is used. Disabling inlining with -qnoinline avoids the issue. ========Testcase: $ cat test.cpp #include <cstdio> struct X { struct Y { int free() { x->y=NULL; return value; } int value; X* x; }; int pop() { return y->free(); } Y*y; }; int main() { X x; X::Y y; y.x=&x; y.value=8200; x.y=&y; printf("%d\n", x.pop()); } $ ===== ACTUAL OUTPUT: $ xlC -O2 test.cpp $ ./a.out 0 $ ===== EXPECTED OUTPUT: $ xlC -O2 test.cpp $ ./a.out 8200 $
Local fix
Use -qnoinline as a workaround.
