A valid pointer value can become invalid if the object to w.
You need to look through your code to work out how this could happen and fix it up.Īlso, you didn't paste the full log or it got truncated by the pastebin. Answer (1 of 5): A pointer value is valid in C++ if: it is a null pointer value, or it points to an object, or it points to code p1/code where code &p0/code points to an object (i.e., one position past an object). However, whenever I created another file, say, myfile.py, and trying to packed it into a class, device selectdevice(opt.device) will fail with this ERROR message: munmapchunk(): invalid pointer. munmapchunk(): invalid pointer How do I fix my munmapchunk(): invalid pointer error It is being printed after my intended output 12-16-2020 2. You're passing a value to sqrt which has not been initialized (i.e. enter a string: never no munmapchunk (): invalid pointer Process finished with exit code -6. I can successfully run yolov5 python detect.py to carry out the test. For example, look at the code in dMath.cpp at line 23.
The others are all saying that you're using memory that has not be initialized with a known value. This is a real heap corruption bug and might be the cause of your problem. This overwrite happens in dInputManager.cpp at line 309. This means you are allocating some memory at line 8 of dInputManager.cpp (in the dInputManager constructor), and later you are writing 4 bytes past the end of the chunk of memory.

They're potential security problems, but we'll ignore them for now. upon returning 0 in main ill get munmapchunk(): invalid pointer: error.
The first two entries might be issues with the system libraries. I tried Valgrind and for what I understand the output it seems not to be my coding error.
