| Description: | ||||
|
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. | ||||
