1. Have you saw crash in real device or only in simulators?
2. Do you use dynamic feature for language ID?

Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

Second crash in the description is from a real device. Experienced it myself on two different Xiaomi phones, plus lots of crashes from users in the Google Play console.
-
Dynamic features are not used in the application.
As a wild guess, I have downgraded build tools from 31.0.0 to 30.0.3, compileSdk from 31 to 30, and moved all work with Language ID to the service in a separate process (just to be sure that crash can kill secondary process instead of main). This combination is in beta for 2 days by now and I don't see any SIGSEGV crashes.

Hmm, I feel the crash might be something related to separate/secondary process.
I also changed compileSdk and targetSDK to 31 but still cannot repro this issue.

On the contrary, there was no separate process before, when crashes started.
In the new build (with the aforementioned changes) I can see SIGSEGV crash, but only one instead of dozens and it has a bit different backtrace:
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
liblanguage_id_jni.so (offset 0x11e000)

Description
OS version: Windows 8.1
Java JRE/JDK version: 1.7.0_51 64bits
gradle version: 1.11
android-plugin version: 0.9.0
NDK version: r9d 64bits
When building ndkJniLib sample from the gradle-samples-0.9 on windows I get this error:
make.exe: *** No rule to make target `C:\Users\xhallade\Desktop\ndkJniLib\lib\build\ndk\release\obj/local/armeabi-v7a/objs/hellojni/C_\Users\xhallade\Desktop\ndkJniLib\lib\src\main\jni', needed by `C:\Users\xhallade\Desktop\ndkJniLib\lib\build\ndk\release\obj/local/armeabi-v7a/objs/hellojni/C_\Users\xhallade\Desktop\ndkJniLib\lib\src\main\jni\hello-jni.o'.
Stop.
If I create a new empty .c file aside hello-jni.c and run gradle again, the .so files are getting generated correctly.
In fact instead of calling gradle again, I can edit myself the generated Android.mk and add the second file to fix this.
When I re-run the ndk-build command line issue by gradle everything compiles fine, so the root cause seem to come from the NDK and not from the build system.
The command issued by gradle:
C:\Android\ndk\ndk-build.cmd NDK_PROJECT_PATH=null APP_BUILD_SCRIPT=C:\Users\xhallade\Desktop\ndkJniLib\lib\build\ndk\release\Android.mk APP_PLATFORM=android-19 NDK_OUT=C:\Users\xhallade\Desktop\ndkJniLib\lib\build\ndk\release\obj NDK_LIBS_OUT=C:\Users\xhallade\Desktop\ndkJniLib\lib\build\ndk\release\lib APP_ABI=all
The generated Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hellojni
LOCAL_SRC_FILES := \
C:\Users\xhallade\Desktop\ndkJniLib\lib\src\main\jni\hello-jni.c \
LOCAL_C_INCLUDES += C:\Users\xhallade\Desktop\ndkJniLib\lib\src\main\jni
LOCAL_C_INCLUDES += C:\Users\xhallade\Desktop\ndkJniLib\lib\src\release\jni
include $(BUILD_SHARED_LIBRARY)
They are the same in both cases - only the reference to the other .c file is added in Android.mk when it's there.
The sample is attached.
