Your program seems to have big mess and memory is getting corrupted. This is is bit difficult to find by looking out your code snippet. However as you have mentioned in your question that you are able to attach your program using Valgrind. So you may want to attach your program(a.out). $ valgrind –tool=memcheck –db-attach=yes … Read more
You have to create a script, lets call it start_valgrind.sh #!/system/bin/sh PACKAGE=”com.example.hellojni” # Callgrind tool #VGPARAMS=’-v –error-limit=no –trace-children=yes –log-file=/sdcard/valgrind.log.%p –tool=callgrind –callgrind-out-file=/sdcard/callgrind.out.%p’ # Memcheck tool VGPARAMS=’-v –error-limit=no –trace-children=yes –log-file=/sdcard/valgrind.log.%p –tool=memcheck –leak-check=full –show-reachable=yes’ export TMPDIR=/data/data/$PACKAGE exec /data/local/Inst/bin/valgrind $VGPARAMS $* that should be copied to the device. Once you have the above script in the start_valgrind.sh file somewhere … Read more
Since python 3.6, there’s a PYTHONMALLOC environment variable which is available in release builds, without needing to recompile. PYTHONMALLOC=malloc python3 foobar.py This will disable pymalloc and just use the libc malloc directly, making it valgrind-friendly. This is equivalent to –without-pymalloc (and it is just as slow) If valgrind is too slow, other values can be … Read more
As there’s no stable release that supports Yosemite, you can install the latest development version with brew install –HEAD valgrind
Use the valgrind option –track-origins=yes to have it track the origin of uninitialized values. This will make it slower and take more memory, but can be very helpful if you need to track down the origin of an uninitialized value. Update: Regarding the point at which the uninitialized value is reported, the valgrind manual states: … Read more
It’s Valgrind’s fault. First, -fsanitize=leak does not show anything. Second, Valgrind itself states that: First of all: relax, it’s probably not a bug, but a feature. Many implementations of the C++ standard libraries use their own memory pool allocators. Memory for quite a number of destructed objects is not immediately freed and given back to … Read more
How to Run Valgrind Not to insult the OP, but for those who come to this question and are still new to Linux—you might have to install Valgrind on your system. sudo apt install valgrind # Ubuntu, Debian, etc. sudo yum install valgrind # RHEL, CentOS, Fedora, etc. sudo pacman -Syu valgrind # Arch, Manjaro, … Read more
There is more than one way to define “memory leak”. In particular, there are two primary definitions of “memory leak” that are in common usage among programmers. The first commonly used definition of “memory leak” is, “Memory was allocated and was not subsequently freed before the program terminated.” However, many programmers (rightly) argue that certain … Read more
As jakobengblom2 pointed out, valgrind has a suit of tools. Depending which one you are talking about there are different windows counter parts. I will only mention OSS or free tools here. 1. MemCheck: Dr. Memory. It is a relatively new tool, works very well on Windows 7. My favorite feature is that it groups … Read more
Valgrind says that the illegal write is occurring at Address 0x6172676f72502074. If you look at that address as ASCII characters, it’s: argorP t, or converting from little endian: t Progra. This looks like part of one of your menu items, “9. Abort Program”. Maybe the bug is that menu_init() is writing past the end of … Read more
