Hi..
I'm using __cxxabiv1::__cxa_demangle() function to demangle the symbols
obtained by backtrace_symbols(). This works almost fine. However, can
somebody explain what does the symbol __gxx_personality_v0 mean?
Consider this example:
class A
{
public:
A() {}
};
class B
{
public:
B() {}
private

I do, I just need to know the backtrace at runtime.

I believe the result is "undefined behavior", so the program might do
anything it wants..

Undefined behavior is undefined behavior, it might work, it might not,
it might format your harddrive..

Hi,
is it possible to turn off -Walways-true warning for certain
comparison?
I have a template with parameter of integral type, which can be both
signed and unsigned and I'm testing the value for <0.. With -Wall
(which I'm using by default) I always get a warning this comparison is
always true when
