[Gambas-user] Signal 11 from programming error

[Jussi Lahtinen]

Hi!
I had error in way I calculated position in array, and it revealed
error in it's handling.
Way to reproduce problem:

Private aa As New Integer[]

Public Sub Form_Open()
aa.Fill(1, -1, 1)
End

gdb outputs:

(gdb) run
Starting program: /usr/local/bin/gbx3 -p
[Thread debugging using libthread_db enabled]

Program received signal SIGSEGV, Segmentation fault.
