Bug ID: 145279
Summary: ByRef argument modified in called Sub is returned
incorrectly
Product: LibreOffice
Version: 7.2.2.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: BASIC
Assignee: [email protected]
Reporter: [email protected]
Description:
The same Basic function executed
1. once with a default argument
2. once with an explicit argument
(both arguments having the same value),
does not show the same behaviour.
See code below that adds 1 to the value 10. The results are
1. 10 (obviously not what is expected)
2. 11
REM ***********************************************
Sub Main()
MsgBox Plus1() ' Displays 10 => NOK
MsgBox Plus1(10) ' Displays 11 => OK
End Sub
REM ***********************************************
Function Plus1(Optional a)
If IsMissing(a) Then a = 10
Add1(a)
Plus1 = a
End Function
REM **********************************************
Sub Add1(ByRef a) ' Note the "ByRef"
a = a + 1
End Sub
Steps to Reproduce:
1. Copy the example code in a Basic module of a new empty document
2. Run the Main() Sub
Actual Results:
1. The value "10" is returned
2. The value "11" is returned
Expected Results:
The value "11" should be returned twice
Reproducible: Always
User Profile Reset: No
