I recently updated Unity to 2019.1.x from 2018.x, and now I can no longer deploy to Android 8 with an IL2CPP release build. The app crash immediately upon launch with errors like this: FATAL EXCEPTION: UnityMain Process: com.whatever.bestappever, PID: 11624 java.lang.Error: signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00000008 Build fingerprint: 'samsung/gts3lwifixx/gts3lwifi:8.0.0/R16NW/T820XXU2BRL1:user/release-keys' Revision: '5' pid: 11624, tid: 11642, name: UnityMain >>> com.whatever.bestappever <<< r0 00000002 r1 00000001 r2 00000000 r3 00004552 r4 c481b170 r5 c456b000 r6 00000000 r7 c6c8e788 r8 00c4b348 r9 00000001 sl 00c4b354 fp c6e7dbe8 ip e9654d5c sp c6e7dba8 lr c5463354 pc c5463330 cpsr e871bd10 at libil2cpp.001d4330(Native Method) at libil2cpp.001d4350(Native Method) I cannot recall that I had this problem when using Unity 2018.x. The app seems to work OK on my galaxy Tab S5e (Android 9) but there are problems on my Galaxy Tab S3 (Android 8), like this: Mono build (Release and Debug) works. IL2CPP Debug build works. IL2CPP Release build crash on launch with the error mentioned above. I have tried with variolous stripping levels and with/without ARM64 support; everything fails when a release build is deployed to my Android 8 device, everything works when deployed to my Android 9 device. I haven't tried with any other devices.
