RE: compiler error

[Wenjin Zheng <wenjin dot zheng at lsbc dot com>]

Hi;

I have narrow down the problem to the assembler.
 
The following program will have an error message from gnu assembler "as"
when compiling on Sun Solaris2.6 using gcc2.95 and libstdc++.a.2.10.0.

//////////////////////////////////////
//problem program
/////////////////////////////////////
#include <string>
#include <map>
using namespace std;

main()
{
    string test("atest"), aKey("theKey");
    map<string, string> aMap;
    aMap[aKey]=test;

    return 0;
}

////////////////////////////////////////////

The gnu assembler on my machine "/usr/ccs/bin/as" gives the error message:
"/var/tmp/ccRKEbwr.s", line 2325: error: can't compute value of an
expression involving an external symbol.

However the following program compiled fine with no error message.

//////////////////////////////////////
//ok program
/////////////////////////////////////
#include <string>
#include <map>
using namespace std;

main()
{
    string test("atest");
    int i=1;
    map<int, string> aMap;
    aMap[i]=test;

    return 0;
}

////////////////////////////////////////////

This only happened on Sun Solaris2.6 (that we use).  On WindowsNT using
VC++6.0 and on Redhat6.1 using egcs2.9.1 everything worked fine.

Does anyone has a clue of what is the problem.  Your help will be greatly
appreciated.

please keep this thread, and replies to it on the libstdc++ mailing
list...

No, i can't tell what's up from any of your previous messages. I'm going
to need code. Sorry
