gdb.log excerpt:

(gdb) PASS: gdb.c++/classes.exp: inherited class param->x
call class_param.Aref_a (g_A)

Program received signal SIGSEGV, Segmentation fault.
0x0804de99 in ClassParam::Aref_a(A&) (this=0x4000185c, a=@0x1) at /horton/chastain/fsf/2001-06-23/source/gdb/testsuite/gdb.c++/misc.cc:434
434       int Aref_a (A &a) { return a.a; }
The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on"
Evaluation of the expression containing the function (ClassParam::Aref_a(A&)) will be abandoned.
(gdb) FAIL: gdb.c++/classes.exp: base class (&param)->a
>How-To-Repeat:
build cvs gdb on native red hat linux 7
use gcc 3.0 as the compiler to run the test suite
run test script gdb.c++/classes.exp
>Fix:
No idea.
