For the last few months, gcc 4.1 has had problems compling
the following code in posRMSDPot.cc in xplor-nih...
IStringStream iNoComments( stripped );
// read NOEPot table
CDSStringStreamBuf<char> dum;
while ( !iNoComments.eof() && !iNoComments.fail() ) {
String word; iNoComments >> word;
if ( word.glob("assi*",1) ) {
PosRMSDPot_Restraint* restraint = new PosRMSDPot_Restraint(this);
iNoComments >> *restraint;
if ( restraint->ok() ) {
restraints_.append( restraint );
if (verbose())
cout << "PosRMSDPot::addRestraints: added restraint: "
<< *restraint << '\n';
} else {
cout << "PosRMSDPot::addRestraints: error adding restraint.\n";
delete restraint;
which generates an error...

String&)':

which is the line "iNoComments >> *restraint;". There also is a compile error

which is the line " << *restraint << '\n';". Any ideas why this breakage has
occured and what the proper workaround is? GCC 4.0.2 doesn't have a problem
with this source as did GCC 4.1 until a few months back.
