Hi there,
I finished compiling g++ 3.1.1 under Redhat 6.2. It took a while but it went
without a hitch. Aside from having to recompile boost in order to work with
my full project I didn't have too many problems. Great!
I'm fixing a whole lot of code that used to compile ok in 2.95.3 and it
doesn't anymore, mostly due to std:: and namespaces conflicts. It's good
that g++ is now stopping us :-)
But I was doing regression testing on one library I had written and found
something weird. I can now reproduce it with only a few lines:
#include <iostream>
int
main()
{
const char* const c1 = "C1";
const char* const c2 = "C2";
const char* const d = NULL;
const char* const c3 = "C3";
std::cerr << "c1 is " << c1 << std::endl;
std::cerr << "c2 is " << c2 << std::endl;
std::cerr << "d is " << d << std::endl;
std::cerr << "c3 is " << c3 << std::endl;
return 0;
}
This is the output:
[anibal@anibal C++]$ g++ -Wall jj.cpp
[anibal@anibal C++]$ ./a.out
c1 is C1
c2 is C2
d is [anibal@anibal C++]$
See? c3 never got printed out. The program seems to terminate when printing
out NULL.
This used to work fine in 2.95.3.
These are my versions:
d is [anibal@anibal C++]$ g++ --version

Can anybody let me know what's going on here?
thanks,
