In function php_intifx_copy_blob there is a problem on line 3249 - there is a memcopy of length "locator_orig->loc_bufsize" while the allocated memory is "locator_orig->loc_size" these values might be different! 

if ((content = emalloc(locator_orig->loc_size)) == NULL) {
    php_error_docref(NULL TSRMLS_CC, E_WARNING, "Can't create blob-resource");
    return -1;
}
memcpy(content,locator_orig->loc_buffer, locator_orig->loc_bufsize);
