Package: libdebian-installer4
Version: 0.80
Severity: serious
File: /usr/lib/libdebian-installer.so.4

At some point between squeeze and wheezy the declaration of
di_release_file.sum has changed from char * to char **. This breaks
the API making it impossible to compile software (e.g. cdebootstrap)
for stable and testing/unstable without ugly hacks. For example in
cdebootstrap the following code is needed:

 if (sizeof(item->sum[0]) == sizeof(char*)) { 
    if (item->sum[1]) 
      return check_sum (target, "sha1sum", (const char*)(intptr_t)item->sum[1],
    if (item->sum[0]) 
      return check_sum (target, "md5sum", (const char*)(intptr_t)item->sum[0],
  } else { 
    return check_sum (target, "md5sum", (const char*)item->sum,

This is an API and ABI breakage requiring a rename to

Alternatively change the declaration of struct di_release_file to

struct di_release_file
    char *filename;                             /**< filename */
    di_rstring key;                             /**< @internal */
  unsigned int size;                            /**< size */
  char *sum;                                    /**< checksum, currently md5 or sha */
  char *sums[2];                                 /**< checksums, currently md5 and sha1 */

filling both sum and sums.

It would be nice to also have some define declared so sources can
check if di_release_file.sums is available. Something simpler than
having to compare the LIBDI_VERSION like

This is only an API breakage and I will not do anything about it.
