Yonghong,

An update on this thread. I successfully reproduced this issue on a
8.2.0 gcc compiler, It looks like gcc 4.9 did not have this issue. I
was also using clang which did not show this bug.

It seems having a DW_AT_specification that refers to another
DW_TAG_variable isn't handled in pahole. I have a (maybe hacky) pahole
patch as fix and let me clean it up and post for review soon.

Hao
