Re: gdb-7.2 c++ break points

[kousiknandy]

Noticing the same problem, is there any workaround? The one noted in OP doesn't 
work for me. 

$ cat 5.cpp
namespace foo {
    int bar (void)  {return __LINE__;}
    int bar (int n) { return n;}
} ;

int main (int ac, char **av)
{
    return foo::bar(__LINE__) - foo::bar();
}

$ g++4 -g -o 5 5.cpp
$ gdb  ./5

I tried "set debug parser" but no useful information can be obtained. 
Interestingly, "disassemble" seems to work:

(gdb) disassemble /m 'foo::bar(int)',+1
Dump of assembler code from 0x80483d6 to 0x80483d7:
3           int bar (int n) { return n;}
   0x080483d6 <foo::bar(int)+0>:        push   %ebp
   0x080483d7 <foo::bar(int)+1>:        mov    %esp,%ebp
End of assembler dump.
(gdb) disassemble /m 'foo::bar()',+1
Dump of assembler code from 0x80483cc to 0x80483cd:

   0x080483cd <foo::bar()+1>:   mov    %esp,%ebp
End of assembler dump.
