File alog-bufferoverflow.patch of Package mpich
copying the string into the first 12 chars of x into c is not needed. xx_write() does exactly the same stuff again later. (line 77) so instead of copying the data here and copy it again later we pass the full length x to xx_write() and let it cut there.
