Steps to Reproduce
Describe the bug
After upgrading to sentry-android-gradle-plugin 5.11.0, our app started crashing when using GSYVideoPlayer (version 11.1.0) in ijk mode.
The crash happens inside ART’s sampling profiler thread with the following message:
invalid pthread_t 0x6a3e8e4730 passed to pthread_getcpuclockid
Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 25681 (Sampling Profil), pid 22954 (com.httest.f1)

To Reproduce
Steps to reproduce the behavior:
Add GSYVideoPlayer 11.1.0 to project, configured in ijk mode.
Upgrade sentry-android-gradle-plugin to 5.11.0.
Run app and play a video.
App crashes within seconds.
Environment
Sentry Android Gradle Plugin: 5.11.0
GSYVideoPlayer: 11.1.0 (ijk mode)
Android version: 15 (AP3A.240905.015.A1)
Device: vivo PD2405B
Reproducibility: ~100% when profiling enabled
Additional context
Disabling profiling (profilesSampleRate = 0.0) avoids the crash.
Older versions of Sentry SDK did not have this issue.
GSY (ijk mode) spawns multiple native pthreads for FFmpeg; it seems Sentry’s sampling profiler races with thread teardown, passing an invalid pthread_t to pthread_getcpuclockid.
Workarounds tried
Turning off performance profiling avoids the crash.
Reverting to an older Sentry version avoids the crash.
Request
Please confirm whether this is a known issue in the sampling profiler integration with native pthreads (ijkplayer/GSY), and if there’s a fix planned or recommended workaround.
Expected Result
App should not crash when profiling is enabled.
Actual Result
App crashes within seconds.

hi @hurist! Yes, it's a known issue sadly, that likely comes from native libraries not detatching native threads correctly. Would you mind sharing a reproducible example with us? That would greatly help to reproduce it and fix it Also, what happens if you clear cache/data of your app? Does it continue to crash consistently?
This issue has gone three weeks without activity. In another week, I will close it.
But! If you comment or otherwise update it, I will reset the clock, and if you remove the label Waiting for: Community, I will leave it alone ... forever!
