Confirmed, not a regression. 2.95.3 rejects the code too.

We get an ICE building a real C++ app.
Thanks to mec for the minimized testcase, which I will attach.
Building it with gcc-4.0.1 and last week's gcc-4.1 snapshot
produces the errors shown below.
gcc-4.0.1:
i686-unknown-linux-gnu-g++ -c b2.cc
b2.cc: In instantiation of 'Beta':

In section 4.2 of DWARF STD, it says that:
A Fortran common block may be described by a debugging information entry
with the tag DW_TAG_common_block.
But it seems that both gfortran and g77 didn't conform to this. This makes
trouble for debugging common block. Here is a testcase to verify thi

Sorry we didn't test with our app before gcc-4.0 was released.
We'll try to do better for gcc-4.1.
This bug affects the use of libstdc++, too, for what it's worth:
