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++?
Hello,
your code is wrong. Libraries that use pointers as iterators will fail.
Libraries that use classes are likely to work. There is nothing wrong with
the fact that libstdc++ accepts this code.
When references on member functions are implemented, it would be possible
to reject this code, but I am not sure we want to.
