You can't, and ideally this shouldn't even be necessary. In the past 
years, people have implemented support in GDB for Fortran and ADA arrays 
that also have dynamic length counts. We should update our DWARF code to 
properly describe the dynamic length location too, so GDB will 
automatically do the right thing (to be enabled/disabled via a -gXXX 
command line option, so the old method can still be selected for use 
with older GDB versions).

Hi,
For a "array of integer" type variable FPC 32bit stabs returns for gdb "ptype"
command
"
type = ^(array [0..-1] of LONGINT)
".
MSEide uses this info to fetch the itemcount and item memory and to show the
array  items in watches window.
FPC 64bit dwarf "ptype" returns
"
type = ^LONGINT
".
How can we identify a dynamic array with FPC dwarf?



If I remember correctly then you can do (after you got above result)
   ptype foo^
or if foo is an expression ptype (foo)^
and this will return an array as ptype.
