It has a check for filtering out entries that have very small overhead (under min_pcnt). However it just assumed the entries are sorted by the overhead so when it saw such a small overheaded entry, it just stopped navigating as an optimization. But it's not true anymore due to new --fields and --sort optoin behavior and this case users cannot go down to a next entry if ther's an entry with small overhead in-between.

The Android system is organized with system libraries found in /system/lib and user libraries in /data/app-lib. On the host system (not running Android), system libraries can be found in the downloaded NDK directory under ${NDK_ROOT}/platforms/${APP_PLATFORM}/arch-${ARCH}/usr/lib and the user libraries are installed under libs/${APP_ABI} within the apk build directory. This patch makes running the reporting tools possible on the host system using the libraries from the NDK.
