ISSUE: 7380
|

|
|
TITLE: Aliased blob variable with less restrictions makes text blob accept malformed string through BLOB_APPEND
|
||
|
|
NOTES:
|
||
|
|
[16.02.2023] pzotov
|
||
|
|
Confirmed bug on 5.0.0.821, 4.0.3.2873
|
||
|
|
Checked on 5.0.0.938, 4.0.3.2876 -- all fine.
|
||
|
|
::: NOTE :::
|
||
|
|
If script is executed from command line using ISQL then problem looks as described in the ticket.
|
||
|
|
But if the same script is executed from firebird-qa then FB 5.0.0.821 crashes.
