Hi,

In my branch and cut, I am assigning memory to 2 problems in my cut callback function by
'{CPXLPptr copy_slp[2];
for (int i=0;i<2;i++)
{
copy_slp[i] = CPXcloneprob (env_slp, slp[i], &status); // this creates a copy of slp problem
if ( status ) goto TERMINATE;
}
}'

At the end of my cut callback function, I free memory by:
'{
for(int i=0;i<2;i++)
if ( copy_slp[i] != NULL ) {
status = CPXfreeprob (env_slp, &copy_slp[i]);
if ( status ) {
fprintf (stderr, "CPXfreeprob failed , error code %d.\n",
status);
}
}

}'
I am still struggling with installation of purify. So, I have not been to confirm this memory leak by purify yet though I am trying to do it.

On the other side, If I deactivate this part of my code, there will not be any memory issue.
Is there anything wrong with the way I am freeing memory?

Thanks,
Amin

By the way, I could install a trial version of Purify, and it shows a memory leakage in this part.

I don't see any obvious mistake in your code (except that you should initialize the copy_slp[2] = {NULL, NULL} to get correct error handling). Where does the "env_slp" come from?

Unfortunately, initializing copy_slp[2] did not solve the issue!

env_slp is an environment which is defined out of my cutcallback function, then I pass it to my cutcallback function in order to solve several cut generation linear programmings in my cutcallback function.
For sure, you remember I am implementing branch and cut:)

Sorry,my bad!
I found the source of issue, it is not related to functionality CPXfreeprob!

Thanks again,
