--- Comment #8 from Rolf Eike Beer <e...@sf-mail.de> ---
I get the same problem using gcc 4.5, 4.7, and 4.8 on a Sun Fire V240 running
Gentoo. Even if the compiler says "Gentoo" it is built with use flag "vanilla",
i.e. without any Gentoo patches.
The test code is simply:
#include <iostream>
int main(void) {
std::cerr << "test";
return 0;
}
Which will output "test" and then segfault. I can reproduce this at will and
can give you further information (traces, asm, poking with gdb, whatever), just
ask. I have tried it with both binutils 2.23.1 and .2, the result is the same:
buildbot@alrakis ~ $ g++ -v -save-temps -g test.cpp -mcpu=native
Using built-in specs.
