RFR: JDK-8160354: uninitialized value warning and VM crash are occurred with GCC 6

[Yasumasa Suenaga]

Hi all,

This review request relates to JDK-8160310: HotSpot cannot be built with GCC 6 .

I encountered 2 compiler warnings and 2 VM crashes when I compiled OpenJDK 9 with
GCC 6 on Fedora 24 x64.
I think these error should be fixed.

I uploaded webrev.
Could you review it?

I'm jdk 9 committer, but I cannot access JPRT.
So I need a sponsor.


Thanks,

Yasumasa
