I am getting
free(): invalid pointer
error for all of my OpenCL program that I have wrote with ROCm 6.0.2. I am using AMD Radeon Pro WX3200, and it is identified by the rocminfo like below.

The code compiles fine without any major error, and I have ran the same code without any issues in the past. But, with ROCm 6.0.2, I can’t get it to work. Here is short snippet of my code.
#include <stdio.h>
#include <stdlib.h>
#define CL_TARGET_OPENCL_VERSION 200
#include <CL/cl.h>
#include "cl_err.h"
// netCDF constants
#define err(e) {printf("Error: %s\n", nc_strerror(e)); return(2);}
#define clerrchk(arg, e) {printf(" %-40s : %s\n",arg, geterrstr(e));}
#define debug(line) {printf("Here? Line : %d\n",line);}
int main()
{
int i;
// OpenCL part //
// Use this to check the output of each API call
cl_int status;
// Retrieve the number of Platforms
cl_uint numPlatforms = 0;
status = clGetPlatformIDs(0, NULL, &numPlatforms);
The error seems to be occurring at
status = clGetPlatformIDs(0, NULL, &numPlatforms);
which means that there is a problem with the OpenCL stack with ROCm 6.0.2. I have tried to set the environment variable ROC_ENABLE_PRE_VEGA=1 since my card is gfx803, but I am still getting the same result.
Does anyone know how to work around this issue? Thanks.
