When porting a new android device base on AOSP 5.0.1, we experience random
crash across Java process.
>From tombstone we see it mostly cause by GC check memory, such as
backtrace:
#00 pc 00127e90 /system/lib/libart.so
(art::gc::collector::MarkSweep::ProcessMarkStack(bool)+183)
#01 pc 001284a1 /system/lib/libart.so
(art::gc::collector::MarkSweep::MarkingPhase()+112)
#02 pc 0012856f /system/lib/libart.so
(art::gc::collector::MarkSweep::RunPhases()+158)
#03 pc 0011fad1 /system/lib/libart.so
(art::gc::collector::GarbageCollector::Run(art::gc::GcCause, bool)+232)
#04 pc 0013d1e7 /system/lib/libart.so
(art::gc::Heap::CollectGarbageInternal(art::gc::collector::GcType,
art::gc::GcCause, bool)+1398)
#05 pc 0013e5a9 /system/lib/libart.so
(art::gc::Heap::ConcurrentGC(art::Thread*)+48)
#06 pc 000003df /data/dalvik-cache/arm/system@[email protected]
Sometimes it fails on JNI check:
backtrace:
#00 pc 0003db54 /system/lib/libc.so (tgkill+12)
#01 pc 00016db9 /system/lib/libc.so (pthread_kill+52)

#05 pc 00216361 /system/lib/libart.so (art::Runtime::Abort()+160)
#06 pc 000a6d75 /system/lib/libart.so

#07 pc 000b09d5 /system/lib/libart.so (art::JniAbort(char const*, char

#08 pc 000b0f1f /system/lib/libart.so (art::JniAbortF(char const*,
char const*, ...)+58)
#09 pc 001c10bf /system/lib/libart.so
(art::JNI::ReleaseIntArrayElements(_JNIEnv*, _jintArray*, int*, int)+470)
#10 pc 000140f1 /system/lib/libjavacore.so
The crash usually caused by access invalid memory or GC detect invalid
access.
We know this may be caused by head corruption, but it is very hard to find
who trashes the memory.
We follow the instruction from Google pages but still no good luck.

Any suggest to fight such kind of bugs?
