GDB also has some other problems while working with gfortran, such as the 
printing of one-dimensional array, function evaluation, handling of common 
block variable and so on...

Some of these problems stems from the DWARF output of gfortran, some lies 
in the code of gdb, some might involve both.  I has been working on some 
of these problem at gdb's side.  I am now thinking of whether there are 
any specific requirement from gfortran community for GDB.  Did any of you
have a big picture about how well gdb work with gfortran?  Did you 
have a list of things that want GDB to support first?  Part of my effort 
is to extend gdb's testsuite with reference to gfortran compiler.  So I am 
very happy to receive any feedback on these.  Thanks a lot in advance.
