(internal Firebird consistency check) on selecting records
---------------------------------------------------------------------------------------------------------------------------------
Key: CORE-3865
URL: http://tracker.firebirdsql.org/browse/CORE-3865
Project: Firebird Core
Issue Type: Bug
Components: Engine, GBAK
Affects Versions: 2.5.1
Environment: Firebird 2.5.1.26351 x64, Windows 7 Professional 64-Bit
(German), 4 GB RAM
Reporter: Daniel Bauten
The Table {{K_ACT_AFD_STRING_DATA}} seems to be corrupt. Therefore, backing up
the database is not possible, i.e. leads into Bugcheck 179 (decompression
overran buffer). Selecting all records of {{K_ACT_AFD_STRING_DATA}} leads into
internal Firebird consistency check.
To reprocude, please do the following.
# Extract {{Corrupt table K_ACT_AFD_STRING_DATA.7z}} (please note: file is
password protected; please mail to Daniel.Bauten(a)hksinformatik.de to obtain
the password).
# running gbak in the following manner
{code}
"%FirebirdPath%\bin\gbak.exe" -b -g -v -y "%BackupLogFile%" -user "%User%"
-password "%Password%" "%DatabaseFile%" "%BackupFile%"
{code}
leads into
{code}
gbak: ERROR:internal Firebird consistency check (decompression overran buffer
(179), file: sqz.cpp line: 228)
{code}
on table {{K_ACT_AFD_STRING_DATA}}
# trying
{code}
select count(*) from K_ACT_AFD_STRING_DATA
{code}
leads into server crash
{code}
internal Firebird consistency check
{code}
Feel free to contact me if you have further questions about this issue.
