Request for Approval: Backport of JDK-8205965: SIGSEGV on write to NativeCallStack::EMPTY_STACK

[Leslie Zhai]

Hi Zhengyu,

Thanks for your sponsor!

I will run jtreg towards:

* jdk8u-dev, base on 8722:16b9bbfaa450, applied with the patch, compiled 
with clang-6 and clang-8-dev

* jdk8u-dev, base on 8722:16b9bbfaa450, compiled with gcc-6.4.3 and 
gcc-9-dev

Then run jtdiff on Linux X86.

Hi Dimitry,

Please verify the patch on FreeBSD compiled with clang-6, thanks a lot!

Thanks,

Leslie Zhai
