As I wrote in a reply on a different thread that has the same purpose as this one...
When debugging memory management problems in C/C++ code there are many tools to assist in understanding the problem. The first, and usually easiest to use is to enable your platform "debug" version of the malloc subsystem. Type "man malloc" to find out which env vars, if any, your platform provides to enable these features. Second is "valgrind". Third, and by far the most useful (i.e., helpful) tool, is ASAN: the address sanitizer. I haven't needed to use this tool with cgo code so I can't explain how to use it with cgo. My google search results yielded some results (e.g., https://grokbase.com/p/gg/golang-dev/133rert6kv/using-addresssanitizer-with-go) that imply it is at least theoretically possible to use ASAN with go. At the end of the day you are asking us to debug your code for free. Most of use are happy to help if the problem is described in a way that allows us to reproduce the problem. Or, is so simple (once you know the answer) that composing an answer doesn't take much more time than reading the original question. Your situation does not match either of those possibilities.
