Pritpal:
I do not know where to experiment:
"qMsgBox := QMessageBox():new( qMainWindow )"
In demoqt.prg after main()
MsgInfo( "Testing" )
Using in demoqt.prg
[...]
HB_TRACE( HB_TR_ALWAYS, ( "-----------------b-----------------" ) )
//DAVID:
MsgInfo( "Testing" )
FOR i := 1 TO 1
oWnd := QMainWindow():new()
[...]
running demoqt.exe it show message window and crash after pressing OK
button with output:
-----------------------------------
demoqt.prg:127:MAIN(): HB_TR_ALWAYS
demoqt.prg:128:MAIN(): HB_TR_ALWAYS -----------------b-----------------

-----------------------------------
Current code is:
[596] STATIC FUNCTION MsgInfo( cMsg )
LOCAL oMB
oMB := QMessageBox():new()
oMB:setInformativeText( cMsg )
oMB:setWindowTitle( "Harbour-QT" )
oMB:exec()
[604] oMB := NIL
HB_GCALL( .T.)
[607] RETURN nil
so line 604 is:
oMB := NIL
Using:
//DAVID: oMB := NIL
crash again after OK button but now in line 607 which is:
RETURN nil
with output:

-------------------------
so in this test both crashes are within MsgInfo() function trying to
clean/discard oMB object
Did you checked "OS/2: Harbour 14019" message ?
