TITLE: Removing first column with SET WIDTH crashes ISQL
|
|
DESCRIPTION:
|
|
NOTES:
|
|
[14.11.2023] pzotov
|
|
There are no crashes on FB 3.x ... 6.x neither on Windows nor on Linux.
|
|
Crash occurred only in DEBUG build (reply from Adriano, 14.11.2023 12:18).
|
|
On release build, 'set width a;' caused missing info about width for column 'b'.
|
|
Confirmed bug on WI-T6.0.0.122.
|
|
Checked on 6.0.0.124 (intermediate build, timestamp: 14.11.2023 09:00).
