fortran arrays in gdb

[Patrick Alken]

Hi,

  I have tried the latest snapshot: GNU gdb 6.6.50.20070305
but it has the same behavior has 6.5:

(gdb) p a
$5 = (PTR TO -> ( real*8 (1,1))) 0xbf85dbd0

Since the matrix "a" has a dynamically specified size:

double precision a(n,n) where n is an input parameter, maybe
gdb cannot determine how big it is, since the "print a" command
is telling me its a 1-by-1 matrix. Is there a way to "tell" gdb
what the leading dimension of the array is, so that a(x,y) will
work correctly?
