zero debug still broken after 8189871 (original) (raw)

Hi all,

seems that "8191663: Zero variant broken after 8189170 and 8189871" was alone not sufficient to fix zero debug.

When building zero (fast|slow)debug, I get this error:

on Ubuntu 16.4. x64

The error also happens in slow and fastdebug, with precompiled headers enabled or not. Release is fine (in a fashion, I need disable-warnings-as-errors to get it built, but I guess that is another bug).

Thanks, ThomasIt seems triggered by "8189871: Refactor GC barriers to use declarative semantics", but I stared at this error message for half an hour now with not much progress... I do not really understand why the STATIC_ASSERT is failing here. Does anyone have an idea?

Thanks, Thomas
