            Bug ID: 128263
           Summary: Using trailing "_" with If statement breaks line
                    positioning when debugging
           Product: LibreOffice
           Version: Inherited From OOo
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: BASIC
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: mikekaganski at hotmail.com

In a new Basic module, replace all boilerplate with this code:

Function Foo()
    If 0 Then print 1
    If 0 Then _
        print 1
    If 0 Then _
        print 1
End Function

Sub Bar
    print "Bar"
End Sub

Note that all If statements there are using single-line syntax without EndIf,
and last two of them are written in two lines each, with "_" to break the line
into two.

Now try to put cursor into Bar, on the line with "print 1", and press F5 to run
it. Instead of executing it, it will open LibreOffice Basic Macros dialog, as
if you had put cursor outside of any macro.
The same result would be when you put cursor to the last line of Bar (with "End
Sub"), but Bar would run if you put cursor to "Sub Bar", *or to the line just
above*, or even *if you put cursor to the last line of Foo (with "End
Function")*! This shows that IDE treats lines incorrectly, shifting by 2 lines.

If you replace any of the two-lined Ifs into a single-lined If (to look like
the first If), then the shift will become 1 line; and replacing both 2-lined
Ifs with 1-lined variant makes it all OK.

Also the same problem is with putting breakpoints.

Tested with Version: 6.3.3.1 (x64)
Build ID: f41f4c7f9507aeca13cb9df51f34d80e8ba30a99
CPU threads: 12; OS: Windows 10.0; UI render: GL; VCL: win; 
Locale: ru-RU (ru_RU); UI-Language: en-US
Calc: threaded

and also with OpenOffice.org 3.2.0 OOO320m12 (Build:9483) - in that old
version, only Main is run when you press F5, so the problem is only visible as
breakpoint displacement.
