Can GDB be used to print values of allocatable arrays of a derived type in Fortran 90?

GDB users,
I just posted this question to Stack Overflow:
http://stackoverflow.com/questions/16447741/can-gdb-be-used-to-print-values-of-allocatable-arrays-of-a-derived-type-in-fortr
I have the following data structure in a Fortran90 program:
TYPE derivedType
CHARACTER(100) :: name = ' '
INTEGER :: type = 0
REAL(KIND(1.0D0)) :: property = 0.0
END TYPE derivedType
TYPE (derivedType), ALLOCATABLE, DIMENSION(:) :: arrayOfDerivedTypes
When I try to debug and print values in GDB like:
(gdb) p arrayOfDerivedTypes(1)%name
I get non-sensical values (often stings of zeros, forward slashes and
letters), or completely wrong values (like arrayOfDerivedTypes(1)%name
= 9, when I know that it is = 2). How can I get GDB to print the
correct values?
Background
I am aware of:
this bug: http://sourceware.org/bugzilla/show_bug.cgi?id=9395
this branch of GDB: http://sourceware.org/gdb/wiki/ProjectArcher
and this blog post on printing allocatable arrays:
http://numericalnoob.blogspot.be/2012/08/fortran-allocatable-arrays-and-pointers.html
I don't want to go through the trouble of compiling a separate branch
of GDB to test if it solves this problem if someone already knows that
it won't or if there is a better solution available.
Please let me know (either here or on Stack Overflow) if you have any
suggestions.
