"Cannot delete class ..." error occures when cached_compile method is executed.

Line 264 may be wrong.

if(cache_entry->data.file.classes) {
    for(ii = 0; ii < i ; ii++) {
        uninstall_class(cache_entry->data.file.classes[i] TSRMLS_CC);
    }
}

->

if(cache_entry->data.file.classes) {
    for(ii = 0; ii < i ; ii++) {
        uninstall_class(cache_entry->data.file.classes[ii] TSRMLS_CC);
    }
