--- Comment #6 from Raju Ponnagani <shivaraju173ponnag...@gmail.com> ---
Hello Paul Floyd,
I tried the same leak application with Valgrind 3.20 version in android(arm32
bit architecture) and this time the leaked summary is not generated. please
check the below report.
Valgrind command execution:-
valgrind --tool=memcheck --leak-check=full --show-leak-kinds=all
--show-reachable=yes --track-fds=yes --trace-children=yes --track-origins=yes
--smc-check=all --extra-debuginfo-path=path --fullpath-after=string
--demangle=yes --num-callers=20 --show-below-main=yes
--log-file=/data/local/data.txt -v /system/bin/leak-test

==28938== Your program just tried to execute an instruction that Valgrind
==28938== did not recognise. There are two possible reasons for this.
==28938== 1. Your program has a bug and erroneously jumped to a non-code
==28938== location. If you are running Memcheck and you just saw a
==28938== warning about a bad jump, it's probably your program's fault.
==28938== 2. The instruction is legitimate but Valgrind doesn't handle it,
==28938== i.e. it's Valgrind's fault. If you think this is the case or
==28938== you are not sure, please let us know and we'll try to fix it.
==28938== Either way, Valgrind will now raise a SIGILL signal which will
==28938== probably kill your program.
