confusion about string.erase( --string.end() )

[Pawel Sikora <pluto@xxxxxxxx>]

Hi,

afaics the gcc-4.6 accepts following code:

#include <string>
int main()
{
        std::string line( "blabla" );
        line.erase( --line.end() );
}

but other compilers reject such code:

msvc8  : error C2105: '--' needs l-value
comeau : error: expression must be a modifiable lvalue

is it a bug in g++?

BR,
Paweł.
