This is the same bug I reported some weeks back, but with a clear
example:

kewill% cat gdb-bug.cc
class foo
{
public:
  void x(class bar* ...);
};

void main() {}

I compile this on a Sun 3/280 running SunOS 3.5:

kewill% g++ -v -g gdb-bug.cc
g++ version 1.35.1-
 /usr/local/lib/gcc-cpp -+ -v -undef -D__GNU__ -D__GNUG__ -D__cplusplus -Dmc6800

/usr/local/lib/gcc-gnulib -lg -lc


I run the debugger and try to set a breakpoint:

kewill% gdb a.out

(gdb) break main
Segmentation fault (core dumped)
kewill%

I believe the problem is with the parameter list, which has 
"21=*22=xsbar:;" in it, and the debugger expects to see a comma
after bar (This is in dbxread.c, line 3568).

My gdb is gdb 3.1.2, with some patches supplied by Ron Guilmette.
