Subject strange database corruption
Hi all,

I have an application written in Delphi 5. Backup of database is done
with TIBBackupService (InterBase Express).

AFTER the backup ( backup file is ok...) database file get corrupted,
and this is the server log:


SERVER (Server) Wed Jul 24 08:43:12 2002
internal gds software consistency check (decompression overran buffer

...and this is the messages doing a command line backup.
gbak: writing data for table D001B10TTESTA

gbak: ERROR: internal gds software consistency check (decompression
overran buffer (179))

gbak: ERROR: gds_$receive failed

gbak: Exiting before completion due to errors

gbak: ERROR: internal gds software consistency check (can't continue
after bugcheck)

Database situation AFTER backup

My customer was using WIN98, firebird 1.0, the was no crash between the
backup and other operation.
A gfix resolved the situation, but i'm a little scared, because i don't
know what could be happened....

Any idea ???
