接入后GP后台Android4.4版本开始出现较多__futex_syscall3异常，本地也偶尔能在首次启动的时候复现，怀疑是在系统资源(cpu/内存)紧缺下，可能会被系统杀死的情况

查看BoostMultiDex的文章是有介绍使用到libdvm.so，怀疑是4.4这个LinearAlloc上限比较低，分配失败导致的crash

using func = int (*)(constchar* fileName, constchar* odexOutputName, void* ppRawDexFile, bool isBootstrap);

void* handler = dlopen("libdvm.so", RTLD_NOW);
dvmRawDexFileOpen = (func) dlsym(handler, "_Z17dvmRawDexFileOpenPKcS0_PP10RawDexFileb");
dvmRawDexFileOpen(file_path, opt_file_path, &arg, false);
