Prevent c-tree Server Unhandled Exception During Update of Compressed Record

c-tree Server terminated with an unhandled exception when updating a compressed record in a HUGE transaction-controlled file (ctTRNLOG or ctPREIMG) at the logical end of file after turning off ISAM key buffers if the transaction had a previous update to the record followed by a savepoint.

The significant factors were:

  • the record was compressed
  • prior to the update where the crash occurred, the same transaction updated the record and then established a savepoint

Compressed records no longer cause this exception.
