bugreport:string error

["a8601248 (Alfred Minarik)" <a8601248@unet.univie.ac.at>]

If this is the wrong place to report bugs, sorry...
but I could not find a better one.

Compiling this,

-----------------------snip
#include <string>
#include <cstdio>

using namespace std;

int main()
{	
	string str1;
	string str2;
	
	str1=string("8-chars_")+"5char";
printf("1:%s\n",str1.c_str());
	str2=str1+"7-chars";
printf("2:%s\n",str1.c_str()); //str1 is gone
	return 0;
}
-----------------------snap

the output of this program should be

1:8-chars_5char
2:8-chars_5char

but is

1:8-chars_5char
2:

with my system:

egcs 1.1.2 (no special compiler options)
libstdc++-2.90.4 (Fifth snapshot)
Linux pc 2.2.5 #4 Wed Apr 21 01:06:44 MEST 1999 i686 unknown
libc-2.0.7

using cout not printf makes no difference, but this confirms
that the error is in string. Changing the length of any 
string-literals make the bug vanish, so this bug is obscure 
enough that it can pass quite some tests; also strings are marked
to work so I decided to report it.
