<pre>Using LLDB-MI built from trunk (also seen with older versions)
Using this sample code:
class MyClass {
public:
int field;
};
int main() {
MyClass obj;
obj.field = 5;
obj.field = 4;
}
In Eclipse, if I step through the code, the value of 'obj.field' is not updated
in the views. Looking at the MI traces, it looks like when the -var-create is
done on 'obj', correctly but -var-update doesn’t report the change:
Using LLDB-MI (macOS):
994,853 30-var-create --thread 1 --frame 0 - * obj
994,856
30^done,name="var0",numchild="1",value="{...}",type="MyClass",thread-id="1",has_more="0"
...
581,399 48-var-update 1 var0
581,403
48^done,changelist=[{name="var0",value="{...}",in_scope="true",type_changed="false",has_more\
="0"}]
Using GDB (Linux):
980,932 40-var-create --thread 1 --frame 0 - * obj
980,939
40^done,name="var1",numchild="1",value="{...}",type="MyClass",thread-id="1",has_more="0"
....
749,655 56-var-update 1 var1
749,655
56^done,changelist=[{name="var1.public.field",value="4",in_scope="true",type_changed="false"\
,has_more="0"}]
This is a major issue because it makes debugging non-trivial programs almost
impossible.
