Hi, I upgraded to 12.5 today and found that 3/4 of the codes I’ve been working with written with PGI ACC directives would no longer compile. I’m not sure where in the chain this happened, I think the previous version in use was 12.3, either way, the error was this.

After some confusion, I realized that the compiler had decided that all of my basic int variables were actually char * arrays for some reason. These are the relevant chunks of code.

```
float** omp_kmeans(int is_perform_atomic, /* in: */
float **objects, /* in: [numObjs][numCoords] */
int numCoords, /* no. coordinates */
int numObjs, /* no. objects */
int numClusters, /* no. clusters */
float threshold, /* % objects change membership */
int *membership) /* out: [numObjs] */
...
#pragma acc region for \
deviceptr(data)\
deviceptr(cfo)\
private(index,i,j,k,dist,min_dist)\
copyin(numCoords,numObjs,numClusters,gts,gte)\
copyin(fc[0:numClusters*numCoords])
```

The important point is the numCoords, numObjs, etc. int variables. When the copyin clause is removed, the code compiles successfully in 12.5, where both compile successfully with 11.10 (the other one I have immediate access to). Is this intentional behavior?
