Debugger quits if no current list element, PB 6.30 Beta 6 Windows x64 C backend

[Matheos]

Debugger pauses, then quits on C backend, but graceful error under ASM — with 'The list doesn't have a current element'. I thought it might have been reported already, being fairly easy to reproduce — delete if so.

Out of interest, under PB 6.00, there was slightly different behaviour, reporting invalid memory access, findings below.

Code: Select all

; Turn on debugger

Structure MtStr
  act.i
  stor.i
EndStructure

NewList Mt.MtStr()

If Mt()\act
  Mt()\stor = 1
EndIf

; PB 6.30 Beta 6 Windows x64 C backend
; The debugged executable quit unexpectedly

; PB 6.30 Beta 6 Windows x64 ASM
; The list doesn't have a current element

; PB 6.00 Windows x64 C backend
; Invalid memory access. (read error at address 16)

Same bug here under C-backend. Not fixed ...
