*** TEST RESULTS FOR COMMIT 0a8beaba19a991bbfcf03756c4a150bf9512a164 ***
Author: Yao Qi <yao.qi@linaro.org>
Branch: master

Use delete instead of xfree for varobj_item
In commit 2f408ec (Use ui_file_as_string throughout more), we start to
new varobj_item,
> - vitem = XNEW (struct varobj_item);
> + vitem = new varobj_item ();
but we still use xfree. This causes some ASAN errors,
