kandi X-RAY | drmemory Summary

drmemory is a C library typically used in Utilities applications. drmemory has no bugs, it has no vulnerabilities and it has medium support. However drmemory has a Non-SPDX License. You can download it from GitHub.

Dr. Memory is a memory monitoring tool capable of identifying memory-related programming errors such as accesses of uninitialized memory, accesses to unaddressable memory (including outside of allocated heap units and heap underflow and overflow), accesses to freed memory, double frees, memory leaks, and (on Windows) handle leaks, GDI API usage errors, and accesses to un-reserved thread local storage slots. Dr. Memory operates on unmodified application binaries running on Windows, Linux, Mac, or Android on commodity IA-32, AMD64, and ARM hardware. Dr. Memory is released under an LGPL license and binary packages are available for download. Dr. Memory is built on the DynamoRIO dynamic instrumentation tool plaform.

Weird behaviour of function with malloc() and realloc() resulting in Segmentation Fault

Asked 2020-Jan-27 at 04:18

I have a function named num_to_binary, which is used to convert a decimal number stored in the form of array. The prototype for this function num_to_binary is as below:

void num_to_binary(int *number_b, int size_of_number);

Here:

number_b is pointer to array which stores my number. For example, if I would like to convert the number 12345 to binary, then I will be storing 12345 in number_b as follows:

Answered 2020-Jan-26 at 23:03

There are multiple problems in the code:

you do not check for memory allocation failure
you forget to free tmp_pointer before leaving the function.
you allocate a new array fin_ans to reserve the array tmp_pointer and perform the reverse operation but you do not return this array to the caller, nor do you have a way to return its size. You should change the prototype to return this information.
if the number of zero, the converted number should probably have 1 digit initialized as 0, but you use malloc which does not initialize the array it allocates so tmp_pointer[0] is uninitialized.
you did not provide the code for is_zero() nor divide_by_two(). It is possible that bugs in these functions cause the segmentation fault, especially if the loop does not reach zero and memory is eventually exhausted during this infinite loop.

Asked 2019-Feb-16 at 14:23

I located several unaddressable access errors in my code. I know the line where memory corruption happens and the way to solve the problem however I can't understand what causes these errors.

I used DrMemory to detect memory problems and it pointed unaddressable access errors at lines 90, 95, 105. These lines look as:

ANSWER

Answered 2019-Feb-16 at 12:32

Seems really easy to understand after all the investigation you already did.

If the vector is resized then the memory gets relocated and you're accessing already freed memory on the assignment.
