The bug is systematic with skia_bench, I can reproduce it on snowball with and without libjpeg-turbo.

with arm-linux-androideabi-addr2line tool we are to able to know from where segfault comes.
The command line is:
"prebuilt/linux-x86/toolchain/arm-linux-androideabi-4.4.x/bin/arm-linux-androideabi-addr2line -C -f -e out/target/product/snowball/symbols/system/bin/skia_bench 0000cf98"
the error is located in file (:line) external/skia/bench/BenchTimer.cpp:32

it is the release of this->fGpuTimer

The error occur only at the end of skia_bench so all the performance tests are done the value could be retrieved in android log ($logcat -d)
