AV. Problem in MET_procedure
----------------------------
Key: CORE-4239
URL: http://tracker.firebirdsql.org/browse/CORE-4239
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 2.5.3
Environment: Vista x64. Q6600, 8GB. IBProvider Test System.
Reporter: Kovalenko Dmitry
I executed my old tests (in four threads) and get the (think, reproducible) AV
in Firebird's engine:
Необработанное исключение в "0x0000000140256da2" в "fb_inet_server.exe":
0xC0000005: Нарушение прав доступа при записи "0x0000000000000000".
