for gdb4.7, using .o files produced by host==target==sparc g++2.3.[12],
gdb4.7 generates an
  Internal error: could not find physical static variable named _5Thing$g

here's how:

If a file s1.c containing the definition of a class static member variable
Thing::g is compiled WITHOUT -g, and another file s2.c sees the declaration
of Thing::g (from a shared .h file) and s2.c is compiled WITH -g,
and a breakpoint is is placed in s2.c, and at the breakpoint one asks
for
  print Thing::g
then one gets the error message.
If s1.c is compiled with -g, then everything works as expected.

The files follow.

The problems stems from valops.c:1366; phys_name
has the (presumably) right value "_5Thing$g", but
lookup_symbol doesn't know about that in VAR_NAMESPACE,
and so the error is raised.  I don't know enough
about the architecture of gdb4.7 to suggest a fix.
