I'm trying to use gdb 3.0 (running on VAX Ultrix) to debug C++ programs.
The command:
b ClassName::methodName
causes a crash in decode_line_1 (symtab.c).
One problem is that the parsing is done wrong. The patch below fixes
that problem. However, it still crashes because inheritance does not
work (as mentioned in a previous bug report).
A temporary fix for the latter problem to comment out the lines 1277-1279:
#if 0
if (TYPE_N_BASECLASSES (t))
t = TYPE_BASECLASS(t, 1);
else
#endif
