>Description:
If a C++ program has an inner subprogram, for example a method inside a class defined inside the program, symbol definitions are lost.  In addition, symbol definitions are lost for the inner subprogram.  In dwarf2read.c, it appears that read_func_scope is called recursively to process the inner subprogram, and this recursive call does not correctly restore local_symbols or list_in_scope.  "Fixing" this gets symbols for the outer function, but the inner still has no symbols.

gcc bar.C -o bar -ggdb -O0
gdb bar
br main
run
p rc
step into inner
