The reason is that gfortran treats common blocks as structure. So gdb
can't handle it at this time. gdb expects it treated as
DW_TAG_common_block. I ever opened a bug on this at GCC bugzilla:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23057
Hope that gfortran community could handle this in a near future.
