Can confirm this issue is reproducible in windows. Aidl is exiting with non-zero exit code and without any message

> C:\Users\jeanlucncoelho\AppData\Local\Android\Sdk\build-tools\33.0.0\aidl.exe -pC:\Users\jeanlucncoelho\AppData\Local\Android\Sdk\platforms\an
droid-33\framework.aidl -oC:\Users\jeanlucncoelho\project\build\generated\aidl_source_output_dir\debug\out -IC:\Users\jeanlucncoelho\project\src\main\aidl -IC:\Users\jeanlucncoelho\project\src\debug\aidl -dC:\Users\JEANLU~1\AppData\Local\Temp\aidl7877085528088218597.d C:\Users\jeanlucncoelho\project\src\main\aidl\com\example\helloworld\IRenamed.aidl

> echo $LASTEXITCODE
-1073740940

What is strange to me is this argument

-dC:\Users\JEANLU~1\AppData\Local\Temp\aidl7877085528088218597.d

if I look for it windows will tell me it's there

> ls C:\Users\JEANLU~1\AppData\Local\Temp\aidl7877085528088218597.d


    Directory: C:\Users\jeanlucncoelho\AppData\Local\Temp

But the same thing goes if I replace it with my actual username

 ls C:\Users\jeanlucncoelho\AppData\Local\Temp\aidl7877085528088218597.d


    Directory: C:\Users\jeanlucncoelho\AppData\Local\Temp

and aidl seems to succeed if I replace it with my proper username.

I don't know if we are seeing the same bug.

Comment#1 can you please run the command AGP gives you when it fails (when it says Error while executing process ...\aidl.exe with arguments {-p...}) and the run echo $LASTEXITCODE` and tell me what it says?

@jiyong do you know what might be happening here?

-1073740940 (0xc0000374) is a heap corruption exception on Windows.

It would have been nice if com.android.builder.internal.compiler.AidlProcessor.call provided some stack trace or at least stdout/stderr from the AIDL process which are expected to have erorr/log messages. Then using them we could know where the heap corruption occurred.

I don't think AGP suppresses stdout or stderr from aidl. I tried running it manually and got the same error code from it, with no error message or stack trace.

I was able to reproduce it with the AidlTest project in tools/base. Can we try building a debug version of aidl and replacing it in build tools 33.0.0 in the sdk and seeing if it gives you a stacktrace?

FYI the error only happens on windows as far as I can tell.

I have no experience debugging an app on Windows. AIDL compiler is already built with -g (but unfortunately without -funwind-tables). So, I think you could run the compiler via a debugger (WinDbg?) to see where the program was when the error happens.

I found that heap is sometimes corrupted even with no arguments.

.\aidl.exe; echo $LASTEXITCODE randomly gives 1, -1073740940, -1073741819.

I tried patching main (0x2d1540) to

push 12
pop eax
ret

And it still sometimes crashes. So I guess this should be a problem of some global variables.

With windbg I found mysterious heap corruption. It was full of strings, and they were all freed and filled with feee (Windows's free-heap filling bytes). In the middle of that, there are strange values.

However, still not sure what is the cause.

Filed b/237714065 to track this internally. For now, I suggest we go back to the previous AIDL compiler and update have it in the next minor release of build-tools.

FWIW, we found the root cause.

• AidlNode is destructed when AidlTypeSpecifier is destructed.
• The destruction order between AidlNode::unvisited_locations_ and AidlTypeSpecifier is indetermined.
• On windows builds, AidlNode::unvisited_locations_ is destructed prior to aidl_to_ndk.cpp's AidlTypeSpecifier, resulting in push_back to an already destructed vector.
• On linux builds, AidlNode::unvisited_locations_ is destructed in the end, so there are no crashes.

FYI, we fixed this bug on AOSP: https://android-review.googlesource.com/c/platform/system/tools/aidl/+/2143372

What should we do to close this? Can we update 33.0.0 host tools?

+Raju to organize a release of a new build tools (33.0.1) with the fix

Ah, thanks for the update Raju!

There was mention of a build-tools 33.0.1 below.

But this has not yet come to pass, over a month later.

And now Android 13 has been released. I assume it is not required, but it would seem ideal to move to build-tools 33.0.x while moving to target SDK 33...

I gave up and ripped all the old AIDL out of the code -- as we're currently not using it.

I'm surprised no one is:

1. using AIDL,
2. building on Windows, and
3. wanting to use the latest build-tools

Is there any progress? It is already year-end.

Build tools 33.0.1 is released as of yesterday https://developer.android.com/studio/releases/build-tools

We'll be updating the default in AGP, currently targeting 8.0, but might slip to 8.1 if more problems are found

Punted updating the default to AGP 8.1 as Build tools release with the fix is not ready yet

Isn't this fixed already? Why is this blocking a release when it was fixed in built tools 33.0.1?

Yes, this is now fixed. The default version of build-tools from AGP 8.2 alpha version and onwards should be 34.0.0-rc3 which includes all build tool related fixes.
