Error message in Vim 9 script

[Salman Halim]

Hello,

I'm getting this error in my Vim 9 script in Windows GVim 8.2.2912:

Error detected while compiling C:/vim/Vimfiles/plugin/Test.vim[17]..function TestBrokenCall:
line    8:

E1013: Argument 3: type mismatch, expected string but got bool

Here is a simple duplication script:

vim9script

export def g:BrokenCall( lineNumber: number, insertMode: bool, templateToUse: string = 'defaultValue' ): void
  echo lineNumber
  echo insertMode
  echo templateToUse
enddef

export def g:TestBrokenCall( line1: number, line2: number, templateName: string ): void
  # This works
  # call BrokenCall( line1, 0 )

  # This results in
  # Error detected while compiling C:/vim/Vimfiles/plugin/Test.vim[17]..function TestBrokenCall:
  # line    8:
  # E1013: Argument 3: type mismatch, expected string but got bool
  call BrokenCall( line1, 0, templateName )
enddef

call TestBrokenCall(3, 5, 'ab')

Calling BrokenCall with just two arguments works, but passing in the third argument doesn't. The third argument can be a hard-coded string or the variable. Similarly, having BrokenCall contain a default value for the third parameter doesn't seem to matter, either.

Thank you,

Salman

I can reproduce it. The "export" and "g:" are not needed.
The problem is that converting the number zero to a bool is done at the
wrong stack offset. I'll make a patch.
