Hi，

In file /src/http/ngx_http_upstream.c, function
ngx_http_upstream_finalize_request


// if u->pipe == NULL, ngx_http_file_cache_free(r->cache, u->pipe->temp_file); will dereference a null pointer, it's that right ?

// Regards
// Alex

if (u->store && u->pipe && u->pipe->temp_file
&& u->pipe->temp_file->file.fd != NGX_INVALID_FILE)
{
if (ngx_delete_file(u->pipe->temp_file->file.name.data)
== NGX_FILE_ERROR)
{
ngx_log_error(NGX_LOG_CRIT, r->connection->log, ngx_errno,
ngx_delete_file_n " \"%s\" failed",
u->pipe->temp_file->file.name.data);
}
}

#if (NGX_HTTP_CACHE)

if (r->cache) {

......

ngx_http_file_cache_free(r->cache, u->pipe->temp_file);
}
