Question

我正在Solaris 11上使用g ++ 5.4进行编译，并在Solaris 10上运行。除了未捕获的C ++异常外，其他所有东西似乎都可以正常工作。

在Solaris 11上：

这是我的编译器和操作系统版本：

$ uname -a
SunOS tf-vdevmcps11-d001 5.11 11.3 i86pc i386 i86pc
$ g++ --version
g++ (GCC) 5.4.0
Copyright (C) 2015 Free Software Foundation, Inc.

一个简单的测试程序。

$ cat foo.cxx

#include <iostream>

int main()
{
        try {
                throw 15; // f();
                std::cout << "after f\n";
        } catch (int i) {
                std::cout << "caught " << i << '\n';
        } catch (...) {
                std::cout << "caught unknown exception\n";
        }
}

它可以在此处编译并正常运行：

$ g++ -fabi-version=2 -Wabi -o foo -g -m32 foo.cxx
$ ./foo
caught 15

这些是它使用的动态库：

$ ldd foo
        libstdc++.so.6 =>        /usr/lib/libstdc++.so.6
        libm.so.2 =>     /lib/libm.so.2
        librt.so.1 =>    /lib/librt.so.1
        libgcc_s.so.1 =>         /usr/lib/libgcc_s.so.1
        libc.so.1 =>     /lib/libc.so.1

在Solaris 10上它崩溃：

$ ./foo
terminate called after throwing an instance of 'int'
Abort(coredump)

这是核心文件的堆栈跟踪

$ pstack core
core 'core' of 10550:   ./foo
 fecca427 _lwp_kill (1, 6) + 7
 fec720c3 raise    (6) + 1f

 08051053 _start   (1, 8047c98, 0, 8047c9e, 8047ca6, 8047cad) + 83

以下是动态库：

$ ldd foo
        libstdc++.so.6 =>        /opt/csw/lib/libstdc++.so.6
        libm.so.2 =>     /usr/lib/libm.so.2
        librt.so.1 =>    /usr/lib/librt.so.1
        libgcc_s.so.1 =>         /opt/csw/lib/libgcc_s.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libaio.so.1 =>   /usr/lib/libaio.so.1
        libmd.so.1 =>    /usr/lib/libmd.so.1

两个GNU库来自该软件包的5.5版本：
