>Description:

the use of "template" keyword for template specialisation appearing in a postfix expression (ISO 14882 14.2.4) is causing an internal compiler error.

the attached file, compiled without options, reproduce the ICE.

>How-To-Repeat:

>Fix:
an easy workaround is not to use the template keyword, it works in this case. but when using other compilers (like aCC on HP-UX) it is necessary.
