Using gcc (GCC) 4.1.0 20051026 (experimental), the following code will generate an ICE.
Sorry, I currently don't have the time to test the latest version of gcc. ---------<test.cc>---------- void foo() { int t; switch(t) { case 0: A(); case 1: A(); } } --------------------------- test.cc: In function 'void foo()': test.cc:6: error: 'A' was not declared in this scope test.cc:7: internal compiler error: tree check: expected class 'type', have 'exceptional' (error_mark) in decl_jump_unsafe, at cp/decl.c:2153 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions.
