           Summary: X86_64: Segfault on AA Foreach
           Product: D
           Version: D2
          Platform: x86_64
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: druntime
        AssignedTo: sean invisibleduck.org
        ReportedBy: ibuclaw ubuntu.com



The aligntsize() implementations in aaA.d and object_.d differ, causing a
segfault to occur during runtime.

Relevant ticket against GDC here:
https://bitbucket.org/goshawk/gdc/issue/133/segfault-on-aa-foreach

And fix has already been committed, can you please sync this into to druntime?

Regards

Hrm.. why are there two implementations of the function in the first place? 
I'll take this bug, but what I'd prefer to see is loosing the one in aaA.d and
making the one in object.di/object_.d correct.

You didn't happen to try that, did you?

The one on object.d is a member of struct AssociativeArray(Key, Value), the
other is an internal helper function.

By the way, I have already demonstrated with a compiler/runtime patch, that you
can have an associative array ABI that works on all architectures and doesn't
need that messy alignment stuff (how many bugs did that generate in the past,
present and future?).

Enjoy your bugs, I guess.

Would you happen to know where you demonstrated this? :)

All I can find ABI-wise on AA's is
