Bug ID: 121262

Product: LibreOffice
Version: 6.0.6.2 release
Hardware: x86-64 (AMD64)

Bug demo: spreadsheet to call user defined function ADDUP, function in Module1

User defined functions return one of their calling arguments rather than their
result when VBA support is enabled by declaring;

Option VBASupport 1

at the start of the module.

I note a warning that imported VBA code may not reliably access LibreOffice
objects at
https://help.libreoffice.org/latest/he/text/sbasic/shared/03103350.html

However, this is native code and it does not access objects.

Here is the spreadsheet (also see attached file:

VarA 4
VarB 2
ADDUP =ADDUP(B3,B4)

The user defined ADDUP function was created and stored in the spreadsheet’s own
module, as usual i.e. there should be no issue with the spreadsheet not being
able to see the code.

The function adds 2 numbers.

Function Addup(VarA as Single, VarB as Single) as Single
Addup = VarA + VarB
End Function

The result without VBA support is as expected:

VarA 4
VarB 2
ADDUP 6

VBA support is enabled by adding the following at the start of the module:

Option VBASupport 1

The result with VBA support enabled is that a calling argument is returned, not
the function result:

VarA 4
VarB 2
ADDUP 4

Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

Thanks to Oliver & Xisco for responding.

Issue still present on latest stable version

Version: 6.1.3.2
Build ID: 1:6.1.3~rc2-0ubuntu0.18.04.2
CPU threads: 8; OS: Linux 4.15; UI render: default; VCL: gtk3;
Locale: en-AU (en_AU.UTF-8); Calc: group threaded

Note that the failure to reproduce on 6.1.3.2 by Xisco Faulí was on Ubuntu
16.0.4, not 18.0.4. Maybe there is something being called from the OS that's
causing the problem? I am not a developer, so do not have skills to dig into
this possibility.

Did not want to risk installing 6.2, a pre-release version. Also note that the
test by Oliver Brinzing was on a Windows OS not Ubuntu.
