makensis / logiclib crash

[Marshall7a]

That was just to show the example. Using this instead:

====FILE1.NSH====
!ifdef _FILENUM
!undef _FILENUM
!endif
!define /math _FILENUM ${FILENUM} + 1
!echo `I am include number ${_FILENUM}`
!undef FILENUM
!define FILENUM ${_FILENUM}
${For} $R0 1 5
${Next}

!if ${FILENUM} < 16
!include "file1.nsh"
!endif

...still crashes when filenum is 8.
