            Bug ID: 28380
           Summary: "poke" received signal SIGSEGV, Segmentation fault,
                    printing a two dimensional array
           Product: poke
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: Runtime
          Assignee: unassigned at sourceware dot org
          Reporter: guillermo.e.martinez at oracle dot com
                CC: poke-devel at gnu dot org
  Target Milestone: ---

Steps to reproduce:

1) initialize the following variables:
(poke) var bga = [255UB, 255UB, 255UB] ; var fga = [255UB, 99UB, 71UB] ; var l0
= [bga, fga, fga, bga, bga] ; var l1 = [bga, fga, bga, fga, bga] ; var l2 =
[bga, fga, fga, bga, bga] ; var l3 = [bga, fga, bga, bga, bga] ;  var l4 = l3 ;
 var l5 = l4

2) Create a mem IOS:
(poke) .mem foo
The current IOS is now `*foo*'

3) Write the content of l0 variable to *foo* IOS
(poke) byte[3][5] @ 0#B = l0

4) *foo* IOS was not written correctly:
(poke) dump

00000040: 0000 0000 0000 0000 0000 0000 0000 0000  ................

5) Print the content of l0[0]
(poke) l0[0]

Doing the backtrace in GDB:

#10 0x00007ffff7ed9d7d in pvm_program_beginning (program=0x0) at

However, It doesn't show more information using -g -O0 though. ..sorry for that
:-(
