Fatal signal on starting application #1156

Closed pax0r closed 3 weeks ago

Chaquopy version

15.0.1

Devices or emulators where the issue happens

Zebra VC8300 Android 11 Problem DOES not occur on Android 8.1 devices

Describe your issue

On my Zebra device I got random SEGV_MAPERR crashes. There is no java / python stacktraces only some native ones.

The crash happens on app startup, but not every time. One in few runs app starts and works without any problems.

App is designed as Python backend and Webview which uses that backend. I have found out that before failed run the log is spammed with:

 E chromium: [0514/133256.147880:ERROR:elf_dynamic_array_reader.h(64)] tag not found

but the webview DOES not closes. App is designed in such a way that if Python backend crashes it will restart it self, so app can sometimes (after like 10-20 failed atempts) run without user inference.

EDIT: there is also a SELinux complaint about "somehting": 05-14 14:20:56.255 12432 12432 W linker : type=1400 audit(0.0:28570): avc: denied { search } for name="/" dev="mmcblk0p37" ino=2 scontext=u:r:untrusted_app:s0:c2,c257,c512,c768 tcontext=u:object_r:factory_file:s0 tclass=dir permissive=0 app=io.stabilis.indigo

Devices or emulators where the issue happens

Zebra VC8300 Android 11 Problem DOES not occur on Android 8.1 devices

Which Android 8.1 devices specifically? And does the problem happen on an Android 11 emulator?

Can you reduce your app to a minimal example which still shows the problem, and upload its source code to GitHub?

mhsmith commented 3 weeks ago

If this is still a problem, please post the requested information, and I'll reopen the issue.
