Signed integer overflow produces undefined behavior in C and off_t is a signed type. For predictable behavior, add some checks to protect in advance against overflow. On 32-bit systems ftell as called by buffer_tmpfile_prepare_to_read is likely to fail with EOVERFLOW when reading the corresponding postimage, and this patch does not fix that. So it's more of a futureproofing measure than a complete fix. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> |
