How do I run Valgrind locally?
To run Valgrind, pass the executable as an argument (along with any parameters to the program). The flags are, in short: –leak-check=full : “each individual leak will be shown in detail” –show-leak-kinds=all : Show all of “definite, indirect, possible, reachable” leak kinds in the “full” report.
What are Valgrind errors?
Valgrind reports two types of issues: memory errors and memory leaks. When a program dynamically allocates memory and forgets to later free it, it creates a leak. A memory leak generally won’t cause a program to misbehave, crash, or give wrong answers, and is not an urgent situation.
Is Valgrind ever wrong?
Yes, there are false positives with Valgrind, that’s why it has suppression files for particular glibc and gcc versions, for example. The false positives may arise if you are using older valgrind with newer gcc and glibc, i.e., valgrind 3.3 with glibc 2.9.
How good is Valgrind?
Valgrind is well-known as a tool for finding errors of work with memory. But except this, it also contain number of additional utilities for performance profiling, finding synchronization errors in multi-threading programs and analysis of memory consumption.
Why does Valgrind take so long?
Valgrind basically acts like a virtual machine or virtual execution environment running the program, watching all variables, memory allocations, etc., etc. and therefore will run quite a bit slower than native code.
