SQLITE_FCNTL_SIZE_HINT overflows an array

Changes

  1. Change comment to:

    Due to an inadequately-tested last-minute change prior to the 3.7.6 release, use of the SQLITE_FCNTL_SIZE_HINT file control operation on unix builds where SQLITE_ENABLE_LOCKING_STYLE is 0 (or undefined) and HAVE_POSIX_FALLOCATE is defined will cause an array index to be off by one and will probably result in a segfault.

    The problem was introduced by check-in [51029d8430d2dbc] just prior to the release.

    The work-around is to omit the HAVE_POSIX_FALLOCATE compile-time option from the build. Or, avoid using SQLITE_FCNTL_SIZE_HINT.
