Does this reproduce with r26? r25 is no longer supported.

If this also crashes with r26, attach reproducers mentioned in the crash message (see below for example) to further investigate.

Ok, I'll try with r26. I though r25 was still supported as r26 is in beta according to this.

I though r25 was still supported as r26 is in beta according to this.

Technically it's still supported until r26 comes out, but r26 will be out before we can possibly turn around an r25 fix for this bug. This is explained here: https://github.com/android/ndk/wiki/NDK-Release-Process#support-windows

For it to be a candidate for r25 even if that weren't the case, it'd need to be a regression from r24, and we also can't determine that without the repro case. There's pretty much never a time that we can help if there's no repro case attached.

Ah, I see we got part of the repro stuff, yeah, include the stuff clang creates :) That makes things go much faster. Sorry for misunderstanding!

I've so far seen this fail with NDK versions:

  • 23.1.7779620
  • 25.2.9519653
  • 26.0.10636728

Thanks! That helps clear things up. Reopening since this is still broken.

Thanks for resolving this in upstream @appujee. http://r.android.com/2753660 and http://r.android.com/2755291 cherry-pick this to AOSP.

Fix is merged in r26. I think the toolchain we currently have in master is too old for the fix, but it'll be in the r27 toolchain before it goes to beta 1. Leaving this open until then.

Bump NDK to r26c (#8732)
7368487 
Changes: https://github.com/android/ndk/wiki/Changelog-r26#r26c

  * Updated LLVM to clang-r487747e. See AndroidVersion.txt and clang_source_info.md 
     in the toolchain directory for version information.
  * [Issue 1928](android/ndk#1928): Fixed Clang crash in 
     instruction selection for 32-bit armv8 floating point.
  * [Issue 1953](android/ndk#1953): armeabi-v7a libc++ 
     libraries are once again built as thumb.

`AndroidVersion.txt` contains:

```
17.0.2
based on r487747e
```
