What options are available for c++ memory debugging in OpenBSD?

I believe I have a double delete and some memory corruption happening somehow in my complex c++ application on OpenBSD. I would like to track down the first location my object is deleted, and any points at which deallocated memory is accessed.

I would usually look into valgrind, but it is linux only. Failing that, I would instrument my new and delete operators with some kind of tracking code, but I've been finding it difficult to determine the correct google search for this.

Is there any package for openbsd which will give me information on memory errors? Is there any kind of standard way to redefine new and delete to detect overflows, invalid accesses, double frees?

Solution

  • This helps a lot:

    man malloc

    Debugging options can be enabled system-wide, environment-wide, or program-specific.
