libc++ tests fail with "aligned allocation function of type 'void *(std::size_t, std::align_val_t)' is only available on macOS 10.14 or newer" #39701

From the text that you pasted in, it looks like you're running on Mac OS 10.13, but I'd like to be sure. (You're certainly using the 10.13 sdk) What's the version of the OS that you're running? |
I'm running 10.13.6 |
|
This seems related to r350649 (Committed by Louis) Louis is on vacation (if you're reading this, stay on vacation). So I'll attempt to clean this up tomorrow. |
|
@Hans, I committed a fix in r351625. Because the semantics around aligned allocation have changed a ton between different Clang versions, it's possible there are still configurations that fail, but I haven't managed to recreate one. |
|
As I suggested, I found more cases that fail. But I think I've found them all. I'll follow up tomorrow with a ultimate fix. |
Did this land or is it still work in progress? |
|
Hi Hans, Yes, this was fixed in r351670. Sorry I forgot to update the bug. |
|
Thanks! Merged to 8.0 in r351980. |
Extended Description
I assume this is due to https://reviews.llvm.org/D56445
This came up while testing the new 8.0 branch on mac. Please see the example failure below. The full build log is attached.
