Title:
  memory corruption/crash in 64bit version of 3.8.2

Status in sqlite3 package in Ubuntu:
  Fix Released
Status in sqlite3 source package in Trusty:
  Confirmed
Status in sqlite3 source package in Utopic:
  Fix Released

Bug description:
  From a user of my program I have been submitted a database created by
  sqlite3 3.8.2-1ubuntu2 64bit in Trusty 14.04 that will also crash
  sqlite3. The error message varies a bit. Here is a selection of them:

  *** Error in `sqlite3': malloc(): memory corruption: 0x00007f913a81fb60 ***
  ---
  sqlite3: malloc.c:2372: sysmalloc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 *(sizeof(size_t))) - 1)) & ~((2 *(sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long) old_end & pagemask) == 0)' failed.
  ---
  *** Error in `sqlite3': free(): invalid pointer: 0x00007f418d724150 ***
  ---
  *** Error in `sqlite3': double free or corruption (out): 0x00007fa10c80e570 ***

  The crash is easy to reproduce as it happens straight away when
  querying a specific table. The database works fine with the 32 bit
  version of 3.8.2, and it also works if I run it with the 64 bit
  version in Vivid, so I don't think it is corrupt. I guess that also
  means that the bug has already been fixed upstream. I can send you the
  database if you provide an email to send it to.

  Here is what Valgrind has to say about it:
