Does this happen specifically within your app? Does it happen with a new MAUI UI Template app? Does it happen on a dotnet Android (dotnet new android) app that doesn't use MAUI UI?

mfeingol · 2024-06-17T16:37:51Z

@drasticactions: clean new sample app seems to work with LLVM enabled.

ninachen03 · 2024-06-19T08:06:41Z

Verified this original issue with Visual Studio 17.11.0 Preview 2.0 (8.0.60 & 8.0.3 ). Cannot repro it on android

mfeingol · 2024-06-19T17:11:31Z

I installed VS 17.11.0 Preview 2.0. Was able to repro with 8.0.60. Attempted to install 9.0.0-preview.5.24307.10 and had a bunch of unresolved resources and namespaces when compiling for Android... which I didn't have time to work through so I gave up on that.

tldr, it still repros with the latest VS preview.

PureWeen · 2024-06-28T15:25:08Z

@jonathanpeppers any thoughts?

jonathanpeppers · 2024-06-28T15:30:30Z

I think we can move this to runtime.

@mfeingol you might see if you can get a more detailed log with:

# clear the log
adb logcat -c
# enable more logging
adb shell setprop debug.mono.log default,assembly,mono_log_level=debug,mono_log_mask=all
# make the app crash
# save the log (share it here)
adb logcat -d > log.txt

Later, when you want to disable the logging, call adb shell setprop debug.mono.log "''" or reboot the device.

steveisok · 2024-07-18T15:23:39Z

@mfeingol can you please provide a repro and logs (if possible) so that we can investigate further?

mfeingol · 2024-07-18T18:24:19Z

@jonathanpeppers, @steveisok: sorry for the delay. Here's a log of the crash:

Yeah, we're going to need one. Really tough to tell why even from the logs you posted.

Okay. Who should I add?

steveisok · 2024-07-18T19:30:09Z

Okay. Who should I add?
Myself, @fanyang-mono, and @lambdageek

Doing another pass through the log, I do think you hitting the assertion is significant:

ckroads.Android: * Assertion at /__w/1/s/src/mono/mono/mini/aot-runtime.c:5220, condition plt_entry' not met`

fanyang-mono · 2024-07-18T22:10:38Z

This is a duplication of #95406

mfeingol · 2024-07-18T23:44:05Z

@fanyang-mono: thanks! So I take it:

No repro is needed from my side?
Someone is working on a fix for this?

There may be multiple opportunities to reproduce. I suspect yours might be the easiest. We'll see what's wrong and try to work a fix.

mfeingol · 2024-07-18T23:56:55Z

There may be multiple opportunities to reproduce. I suspect yours might be the easiest. We'll see what's wrong and try to work a fix.

@steveisok: I've invited the three of you to my repo. Pull down https://github.com/mfeingol/sideroads/tree/maui and update the project to build release with LLVM enabled. You should see the crash in an emulator at app startup.

mfeingol · 2024-08-13T03:45:38Z

@steveisok: any luck reproducing this? Thanks.

steveisok · 2024-08-13T21:40:50Z

@mfeingol yeah! We found that our LLVM had function specialization turned on and that messed with our expected mono EH code range. That problem results in the crash you are seeing.

We have fixes for LLVM 16 (.NET 8) and LLVM 19 (.NET 9). The .NET 8 one needs to be shepherded through to make our servicing release.

Here's the .NET 8 fix: dotnet/llvm-project#599
