Weird Native Crash - pid: 0, tid: 0 signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)

问题

I am getting this weird crash on android

*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
pid: 0, tid: 0 >>> com.oimvo.discdj <<<

backtrace:
  #00  pc 000000000001d050  /data/app/com.oimvo.discdj-2/lib/arm64/libavfilter.7.11.101.so (av_fastresampler_resample_s16+1944)

and another similar crash

both are - signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)

first crash is happening in my native code, second is happening somewhere else

I have corrected all possible array map errors, and currently i don't have any errors of mapping

BUT HERE I FIND THE PID AND TID "0" ZERO WHICH IS SOMETHING I CANT UNDERSTAND

Please someone explain me why is the pid and tid 0 reported in the crash, i did checked the functions for any array mapping errors, but i guess here the error is related to process/thread id.

I checked all the signal 11 (SIGSEGV), code 1 (SEGV_MAPERR) questions on stackoverflow, i also encountered SEGV_MAPERR earlier but it was related to some fault address, but here this one is different, i get no fault address here i only suspect that the pid/tid maybe causing this error.

Any help/suggestion will be great. Thanks in advance

Edit: i just now noted that i have other crashes too with pid: 0, tid: 0 and maybe most android 7.0,7.1, Please let me know if someone needs more error logs, i am still confused why the pid and tid is zero

Edit: Please try to understand the question before answering, and let me know if someone needs more info
