[PDF] conditional jump valgrind error

The error message "Conditional jump or move depends on uninitialized value(s)" essentially means Valgrind has determined that the result of your program depends on uninitialized memory. Sometimes you will also see the message "Use of uninitialized value of size N". Valgrind will report errors on line 10.

  • How do you fix conditional jump?

    Conditional jump or move depends on uninitialized value(s)
    This error is caused if you forget to initialize variables before using or accessing them.
    You can usually re-run valgrind with the flag --track-origins=yes to see where the uninitialized value came from.

  • What causes valgrind errors?

    The most common are: Invalid read/write of size X The program was observed to read/write X bytes of memory that was invalid.
    Common causes include accessing beyond the end of a heap block, accessing memory that has been freed, or accessing into an unallocated region such as from use of a uninitialized pointer.

  • What are the types of valgrind error?

    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.

  • What are the types of valgrind error?

    Interpreting valgrind 's Output
    Anything lost means that some heap allocated memory can no longer be reached by your program.
    In general, you do not want to lose track of any memory.
    The Error Summary tells you how many errors occurred during the execution of your program.
