simplified c++ code that crushes gcc

g++ -std=c++0x gcc_bug.cpp -o t
gcc_bug.cpp: In member function ‘int funct::operator()(argTs ...)’:
gcc_bug.cpp:7:2: error: expected ‘;’ before ‘}’ token
gcc_bug.cpp:23: confused by earlier errors, bailing out

in the real (and more complex) code, instead the last error message was :

internal compiler error: Segmentation fault
